• Is it possible to output cache by host name? ie varybyhost or varbyhostheader?

  - by Pure.Krome

  Hi folks, i've got a website that has a number of host headers. Depending on the host header, the results are different - both visually (theme'd) and data. So lets imagine i have a website called 'Foo' - that returns search results (original, eh?). Now, the same code runs both sites. It is physically the same server/website (using Host Headers) :- www.foo.com www.foo.com.au Now, if i goto '.com', the site is theme'd in blue. if i goto the '.com.au' site, it's theme'd in red. And the data is different for the same search result, based on the host name (ie. us results for .com, au results for .com.au) SO .. if i wish to use OutputCaching .. can this be handled / differ by the host name? I don't want to have the first person goto the .com site .. grab the results ... and the a second person goto my .com.au .. same search data .. and get the theme and results for the .com site. Possible?

• Choosing the right web service

  - by Ratan Sharma

  My website currently working in ASP.NET 1.1 Old Process In our database we have huge amount of data stored for a decoding purpose. We have to update this huge set of data table each week(Data is supplied from a vendor). In our website (in asp.net 1.1) we query our database to decode information. New process Now instead of storing data in our database and query them, we want to replace this through the web service, AS now the vendor is supplying us a DLL, which will give us the decoded information. Information on the DLL provided by the vendor The DLL provided, can only be added in 4.0 sites. SO that also impleies that i can not directly add the dll to my 1.1 site. This DLL is exposing certain methods, we simply have to add the DLL refernce in our web service and call the method and fetch the needed information. Thus we will not have to store those information in our database. So which type of web service I should go for (asmx OR WCF) that will use the DLLs provided by vendor to fetch the decoded information ?? Flexibility i am looking for in the web service are: It can be consumed from asp.net 1.1 site directly and also using jQuery ajax. It can be consumed from other web services running on the server. It can be consumed from some windows services running from the server. NOTE : Moreover we have a plan to migrate our website from asp.net 1.1 to 4.0 version in future.So it should be that much supportive for future upgrade.

• How to do a javascript redirection to a ClickOnce deployment URL?

  - by jerem

  I have a ClickOnce application used to view some documents on a website. When connected, the user sees a list of documents as links to http://server/myapp.application?document=docname. It worked fine until I had to integrate the website authentication/security system into my application. The website uses a ticketing system to grant access to its users. A ticket is generated by a web application and needs to be added to the deployment URL querystring, then I have to check at application startup that the ticket given in querystring was right by making another request to the web application. So the deployment URL becomes something like: h ttp://server/myapp.application?document=docname&ticket=ticketnumber. The problem is the ticket is valid only 10 seconds, so I have to get it only after the user has clicked a link. My first try was to have some javascript do the request to get the ticket, generate the proper deployment URL and then redirect the user to this URL with "window.location = deploymentUrl;". It works fine in Firefox, but IE does not prompt the user for installation. I guess it is a ClickOnce security constraints, but I am able to do the redirection when doing it on localhost, so I hope there is a workaround. I have also added the server on the "trusted sites" list in IE options. Is it possible to have that working in IE? What are my other options to do that?

• backbone js or knockout js as a web framework with jquery mobile

  - by Dan

  without trying to cause a mass discussion I would like some advice from the fellow users of stack overflow. I am about to start building a mobile website that gets it data from JSON that comes from a PHP rest api. I have looked into different mobile frameworks and feel that JQM will work best for us as we have the knowledge of jQuery even though a little large. Currently at work however we are using jQuery for all our sites and realise that now we are building a mobile website I need to think about javascript frameworks to move us onto a more MV* approach, which I understand the benefits of and will bring much needed structure to this mobile site and future web applications we may bring. I have made a comparision table where I have managed to bring the selection down to 2 - backbone and knockout. I have been looking around the web and it seems that there is more support for backbone in general and maybe even more support for backbone with JQM. http://jquerymobile.com/test/docs/pages/backbone-require.html One thing I have noticed however is that backbone doesnt support view bindings (declarative approach) whereas knockout does - is this a massive bonus? one of the main reasons for using a mv* for us is to get more structure - so I would like to use the library that will intergrate best with jQuery and especially jQuery mobile. neither of them seem to have that similar syntax... Thanks

• Sharing session variables from http and https versio

  - by tangurena

  I am trying to fix an ASP.NET site that a friend had botched converting from older technologies. To the user, the site appears to have public and secured sections. Behind the scenes, the public and private sites are separate web applications with separate app pools. The difficulty arises because it appears that the applications share the same session IDs (when going from the public to the secured pages, the session ID remains the same), yet none of the (InProc) session variables are getting passed from the public site to the private one. Basically, the workflow consists of the user checking a checkbox ("I agree" type of stuff) on the public site (let's call that page http://www.boring.gov/iAgree.aspx), then logging in on the secured site (let's call that page https://www.boring.gov/login.aspx). The commandments from the parent agency in DC are that the user may not bookmark the login page, the user has to click "I agree" every time they log in, and that the "I agree" stuff has to be on a separate page. What am I missing? How would you do it? Notes: 1 - This is getting hosted on a single Windows 2003 server. 2 - Yes, it is a government agency. 3 - I would have done things very differently if I was doing the conversion, but I wasn't brought in until the poop hit the fan, and it is too late to redo things. 4 - Two previous SO threads that appear to be related, yet don't apply are this and that

• GoDaddy Subdomain Hosting Issue/Question with Disk Access (C#/ASP.NET 3.5)

  - by Vogel

  This isn't a very complicated scenario really, but as I start to type out the problem I'm realizing how convoluted it can become textually. Let me try and be very clear: First, the set up... I have a C#/ASP.NET web application that is publicly facing on my main domain (www), let's call it www.mysite.com. Nothing fancy, just a front-end that connects to SQL to display records. Then, I have a second C#/ASP.NET web application that is secured using forms authentication running on a subdomain, let's call it admin.mysite.com. This is a very light-weight CMS system to administer the public site. Now, the problem... Both of these sites run fine for basic tasks, however, my problem arises when I try to gain access to the file system for uploading. GoDaddy requires subdomains to run as a virtual directories under the main application in IIS (so the subdomains actually resolve/re-direct to www.mysite.com/admin when you type in admin.mysite.com), but because of this I am unable to write to my website root from the subfolder. Let me explain a little more... The CMS system (running as a virtual directory) gives the admin the ability to upload photos for display on the main site, the target folder of which is www.mysite.com/images - when attempting disk access from the root app, I am able to write to the virtual directory, but cannot do the opposite -- that is, write to the root from the virtual directory, getting security violations. If I can only upload to the /admin/ virtual directory, the entire point is moot because it's a secured folder that the public can't see! The only solution I can think of is to upload the files to the /admin/ virtual directory, then call a URL in the root that moves files from /admin/ back to the root, but that is entirely ghetto. I hope this post makes sense. Anyone else experience anything like this? The bottom line is that it seems virtual directories ONLY have access to themselves, and not their parent directories, no matter what credentials are used. Thanks!

• google maps api v2 - dynamic load (tens of thousands of) markers

  - by Adam

  Hello, how made with JavaScript+PHP+MYSQL and Google Maps API v2 dynamic load of markers? atm I have map follow example http://googlemapsapi.martinpearman.co.uk/infusions/google_maps_api/basic_page.php?map_id=8 but my marker_data_01.php (where are all markers listed - look code of example) have atm 4MB and will only have more, and more. So the question is: how load only this markers to marker_data_01.php (of some other modification of it, can be on same file as map, meaningless, I load it all from MySQL atm) what I look now: so for example (I dont know what number will good but I write this only for show what I wanna made OR JUST something like it), so top left corner for example have position: 10, top right corner for example have position: 30, bottom left corner for example have position: 5, bottom right corner for example have position: 15. -- so load only this markers what are in this box 10-30-5-15 with for example GET, and when I move map for example to 17-12-48-20 box then made next GET request and with this mysql quote and download next markers that what I see now, with this I can have map with unlimited markers, and when will be a lot of markers then clustering can link them, so with this ppl dont will need do "preload" of all markers DB (what have 4mb now and will have more), but only download that what they see at the moment, I know that is possible because a lot sites have it but I am not master of code langs, I know only a bit php and mysql (and html) :) // sorry for my english

• Memory Bandwidth Performance for Modern Machines

  - by porgarmingduod

  I'm designing a real-time system that occasionally has to duplicate a large amount of memory. The memory consists of non-tiny regions, so I expect the copying performance will be fairly close to the maximum bandwidth the relevant components (CPU, RAM, MB) can do. This led me to wonder what kind of raw memory bandwidth modern commodity machine can muster? My aging Core2Duo gives me 1.5 GB/s if I use 1 thread to memcpy() (and understandably less if I memcpy() with both cores simultaneously.) While 1.5 GB is a fair amount of data, the real-time application I'm working on will have have something like 1/50th of a second, which means 30 MB. Basically, almost nothing. And perhaps worst of all, as I add multiple cores, I can process a lot more data without any increased performance for the needed duplication step. But a low-end Core2Due isn't exactly hot stuff these days. Are there any sites with information, such as actual benchmarks, on raw memory bandwidth on current and near-future hardware? Furthermore, for duplicating large amounts of data in memory, are there any shortcuts, or is memcpy() as good as it will get? Given a bunch of cores with nothing to do but duplicate as much memory as possible in a short amount of time, what's the best I can do?

• Double script tags in Google Analytics tracking code

  - by Tom

  This is more a curiosity question than anything else... Google instructs to add the analytics tracking code as follows: <script type="text/javascript"> var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www."); document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E")); </script> <script type="text/javascript"> try{ var pageTracker = _gat._getTracker("UA-xxxxxx-x"); pageTracker._trackPageview(); } catch(err) {} </script> I'm wondering some JS guru here could tell me why they're separating it into two script tags instead of sticking it all inside one. I know that the top part could be put in the header and the bottom part just before body tag to ensure the page loaded before it's tracked, but I'm wondering if there's something more to it. Anyone who'd know that would likely know how to separate the code into two tags anyway. I'm only asking as this is coming from the Goog and is being used by millions of sites... Thanks

• Need Help with wxPython & pyGame

  - by Xavier

  Hi Guys, I'm actually in need of your help and advice here on my assignment that I am working on. First of all, I was task to do a program that runs langton's ant simulation. For that, I've managed to get the source code (from snippets.dzone.com/posts/show/5143) and edited it accordingly to my requirements. This was done and ran in pygame module extension. In addition, my task requires a GUI to interface for users to run and navigate through the screens effectively with the langton's ant program running. I used wxPython with the help of an IDE called BOA constructor to create the frames, buttons, textboxes, etc. Basically, all the stuff needed in the interfaces. However, I've ran into some problems listed below: Found problem integrating pyGame with wxPython. On this note, I've research the internet for answers and tutorials where I found out from website: wiki.wxpython.org/IntegratingPyGame & aspn.activestate.com/ASPN/Mail/Message/wxpython-users/3178042. I understand from the sites that integrating pyGame with wxPython will be a difficult task where it has caused common problems like the inability to placing other controls into the frames as the pyGame application will cover the entire panel. I really hope that you can clarify my doubts on this and advise me on the path that I should take from here. Therefore, I ask the following questions: Is it feasible to integrate pyGame with wxPython? If it is not feasible to integrate pyGame with wxPython, what other alternatives do I have to create a GUI interface integrating pyGame into it. If so how do I go about? If it is possible to go about integrating pyGame with wxPython, how do I go about doing so? Really need you guys opinion on this.

• SSL certificate pre-fetch .NET

  - by Wil P

  I am writing a utility that would allow me to monitor the health of our websites. This consists of a series of validation tasks that I can run against a web application. One of the tests is to anticipate the expiration of a particular SSL certificate. I am looking for a way to pre-fetch the SSL certificate installed on a web site using .NET or a WINAPI so that I can validate the expiration date of the certificate associated with a particular website. One way I could do this is to cache the certificates when they are validated in the ServicePointManager.ServerCertificateValidationCallback handler and then match them up with configured web sites, but this seems a bit hackish. Another would be to configure the application with the certificate for the website, but I'd rather avoid this if I can in order to minimize configuration. What would be the easiest way for me to download an SSL certificate associated with a website using .NET so that I can inspect the information the certificate contains to validate it? EDIT: To extend on the answer below there is no need to manually create the ServicePoint prior to creating the request. It is generated on the request object as part of executing the request. private static string GetSSLExpiration(string url) { HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest; using (WebResponse response = request.GetResponse()) { } if (request.ServicePoint.Certificate != null) { return request.ServicePoint.Certificate.GetExpirationDateString(); } else { return string.Empty; } }

• How do I fix this installation problem with multicore Solr on Ubuntu 10.04?

  - by coleifer

  Following instructions from the two sites below, I've installed Tomcat 6 and Solr 1.4. http://gist.github.com/204638 https://wiki.fourkitchens.com/display/TECH/Solr+1.4+on+Ubuntu+9.10+and+CentOS+5 I have successfully got it up and running on a server running 9.04 with multicore support, but on the 10.04 I can't seem to get it to work.

• Hotkeys in webapps

  - by Johoo

  When creating webapps, is there any guidelines on which keys you can use for your own hotkeys without overriding too many of the browsers default hotkeys. For example i might want to have a custom copy command for copying entire sets of data that only makes sense for my program instead of just text. The logical combination for this would be ctrl+c but that would destroy the default copy hotkey for normal text. One solution i was thinking about is to only catch the hotkey when it "makes sense" but when you use some advanced custom selection it might be hard to differentiate if your data is focused, if text is selected or both. Right now i am only using single keys as the hotkey, so just 'c' for the example above and this seems to be what most other sites are doing too. The problem is that if you have text input this doesn't work so good. Is this the best solution? To clarify I'm talking about advanced webapps that behave more like normal programs and not just some website presenting information(even though i think these guidlines would be valid for both cases). So for the copy example it might not be a big deal if you can't copy the text in the menu but when ctrl+tab, alt+d or ctrl+e doesn't work i would be really pissed, cough flash cough.

• Compressing xls content with apache deflate module

  - by Clinton Bosch

  I am trying to compress an excel spreadsheet being sent from my application using apache deflate module. I have added the following line to the my sites-enabled file: AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript application/excel But is seems to make the response data bigger??? Using firebug, without the module I downloaded the xls spreadsheet from the application and it downloaded 100Kb of data, the file size once on the filesystem was also 100Kb as expected. Once I enabled the deflate module as described above and repeated the process, the amount of data downloaded was 295Kb?? but the file was still only 100Kb once save on the filesystem. As an experiment I manually gzipped the saved xls file and it compressed to 20Kb. What am I doing wrong here?

• Getting my foot in the SCADA door, how?

  - by bibby

  I keep hearing that I should learn SCADA and its PLC language to upgrade my career. While I enjoy currently being a web and mobile development privateer, the prospects of working for a municipality or industrial entity has its appeals (since I am trying to grow a family). Over the years, I've tought myself to skillfully use php, javascript, java, perl, awk, bash. Surely, these language skills can tranfer somewhat to SCADA's logic controller language. Without any formal training in CS (music major!) other than at the workplace, I wouldn't have been able to pick up those languages and run with them had it not been for their open documentation and free-to-install or already-installed interpreters/compilers. I can't see that this is true with SCADA, and I'm hoping that I'm wrong. Ideally, I'd like to be able to apply for a job that requires [A,B,C] and suggest that they hire me because I already know [A & B]; that they wouldn't have to do a ground-up training with someone that's never programmed before. So, finally, the question; How do I "learn" SCADA? Are there sites and docs? What's going to help me get my foot in the door? Any insight is appreciated. Thanks!

• Rails - handling global site settings

  - by egarcia

  I'm developing a new rails application which is supposed to be installed several times in order to implement several sites. There are some things, like the "Site Title" or the "Default Number of Items per Page" that clearly belong to a "global settings" table / config file. I've made a list of the things I think I'll need: ActiveRecord model that is capable of: Storing different kinds of data. I suppose this would be accomplished encoding the values on a string on the db, probably with a "type" field. Indexing settings by name Validations based on a "type" attribute (i.e. don't accept invalid dates on "date" settings) Validations based on a allows_nil property. A controller that allows me to change settings via views. I'm pretty sure I could implement this myself, but I'm not willing to reinvent the wheel. I've done some searching, but I could only find rails-settings, which doesn't really serve me: I need a proper model & controller so I can use declarative-authorization, and it does not provide any controller or view facilities. Is there a gem or plugin out there that implements what I want, or any library I should look at? Thanks a lot.

• What is usefulness of W3C's Semantic Data Extractor in semantically correct XHTML CSS Development?

  - by metal-gear-solid

  What is the usefulness of W3C's Semantic Data Extractor? http://www.w3.org/2003/12/semantic-extractor.html This tool, geared by an XSLT stylesheet, tries to extract some information from a HTML semantic rich document. It only uses information available through a good usage of the semantics defined in HTML. The aim is to show that providing a semantically rich HTML gives much more value to your code: using a semantically rich HTML code allows a better use of CSS, makes your HTML intelligible to a wider range of user agents (especially search engines bots). As an aside, it can give clues to user agents developers on some hooks that could be interesting to add in their product. After checking validation for CSS and HTML. Should i go for Semantic Data Extractor tool. What it does. and how it can improved our coding.? Is anyone using it?

• Using Facebook Login to create a user?

  - by andbeyond

  I've read this SO post which led me to this FB policy page, which seemed to include some pertinent information, but I'd like more of a community response, maybe some experienced FB API people who know the limits. My question is if I can use Facebook's Login api to, essentially, create a new user on my website. I really would just like to allow users to easily "transfer" some data from FB in order to more easily create a new account on my site. I realize, first and foremost, that I would obviously announce to the user that by click "submit" in the form, that they are creating a separate account on my site. Pertinent blocks on the policy page state: You may cache data you receive through use of the Facebook API in order to improve your application’s user experience, but you should try to keep the data up to date. This permission does not give you any rights to such data. Which doesn't look good for me, but also this: If you stop using Platform or we disable your application, you must delete all data you have received through use of the Facebook API unless: (a) it is basic account information; or (b) you have received explicit consent from the user to retain their data. Which, in my case, I would be satisfying part B. I would be asking the user's permission to retain the data, as I am simply using Facebook as a conveience to the user when creating an account. I also realize that Facebook has a registration API, but this would require a Facebook styled login form, along with my own sites login form, and I'd rather one interface, as this makes it easier for me on the front and back end. Any thoughts?

• Help, my CentOS servers keep going down , No route to host after a random uptime [closed]

  - by user249071

  Hello , I have a couple of Centos linux servers, that have a very simple task, they run nginx + fastcgi for php , and some NFS mounts between them, readonly They have some RPC commands to start some downloading processes with wget, nothing fancy , from a main server, but their behavior is very unstable, they simply go down, we tried to monitor ram , processor usage, even network connections, they don't load up so much, max network connections up to... 250 max, 15% processor usage and memory , well, doesn't even fill up, 2.5GB from 8GB max , I have no ideea why can a linux server go down like that, they aren't even public servers, no domain names installed no public serving, for sites. The only thing that I've discovered was that if i didn't restart the network service every couple of hours or so... the servers were becoming very slow, starting apps very slow, but not repoting a high usage of resources...Maybe Centos doesn't free the timeout connections, or something like that...It's based on Red Hat right? I'm not a linux expert , but I'm sure that there are a few guys out there that can easily have an answer to this , or even have some leads to what i can do ... I haven't installed snort, or other things to view if we have some DOS attacks, still the scheduled script that restarts the network each hour should put the system back online, and it doesn't.... Thank you in advance

  Hi all, I have worked for various web projects but correct date time localization have not been done and considered throroughly so I want to ask this very typical problem here and I want to hear comments from expert in this problem What is the correct strategy for storing a date/time value from client from server As I understand, because of locale and timezone so we have to do the conversion, I have heard about GMT or UTC time and after do some search it seems that UTC is more accurate ? so we will convert from client time - UTC+0 when saving and when we read the value from server to client, we convert from server time back to client time again ? However, I see in some website, at the bottom have the sentence "All times are in UTC", "All times are in GMT" and also "All times are in your local time". So maybe not all the sites do the convertion back and forth ? And in that case the user has to manually do the date/time conversion ? How to display the date/time convenient to user based on his locale and region How to provide personalization on date/time value ? I had one time depends on vbscript to do the display and the format is read from windows regional and format settings automatically. But without vbscript how can we determine a date/time pattern for a user of a specific locale. Do we have to store a mapping between a locale and pattern somewhere and do the conversion at the server side ? Although date/time conversion is needed in most case, there's situation where only date matter for example if my birthday is 2 Feb 1980, it should be the same for all locale and no conversion should be done. How can we address this issue.

• DataGridView not displaying a row after it is created

  - by joslinm

  Hi, I'm using Visual Studio 10 and I just created a Database using SQL Server CE. Within it, I made a table CSLDataTable and that automatically created a CSLDataSet & CSLDataTableTableAdapter. The three variables were automatically created in my MainWindow.cs class: cSLDataSet cSLDataTableTableAdapter cSLDataTableBindingSource I have added a DataGridView in my Form called dataGridView and datasource cSLDataTableBindingSource. In my MainWindow(), I tried adding a row as a test: public MainWindow() { InitializeComponent(); CSLDataSet.CSLDataTableRow row = cSLDataSet.CSLDataTable.NewCSLDataTableRow(); row.File_ = "file"; row.Artist = "artist11"; row.Album = "album"; row.Save_Structure = "save"; row.Sent = false; row.Error = true; row.Release_Format = "release"; row.Bit_Rate = "bitrate.."; row.Year = "year"; row.Physical_Format = "format"; row.Bit_Format = "bitformat"; row.File_Path = "File!!path"; row.Site_Origin = "what"; cSLDataSet.CSLDataTable.Rows.Add(row); cSLDataSet.AcceptChanges(); cSLDataTableTableAdapter.Fill(cSLDataSet.CSLDataTable); cSLDataTableTableAdapter.Update(cSLDataSet); dataGridView.Refresh(); dataGridView.Update(); } In regards to the DataSet methods I tried calling, I had been trying to find a "correct" way to interact with the adapter, dataset, and datatable to successfully show the row, but to no avail. I'm rather new to using SQL Server CE Database, and read a lot of the MSDN sites & thought I was on the right track, but I've had no luck. The DataGridView shows the headers correctly, but that new row does not show up.

• Umbraco template issues

  - by bomortensen

  Hi fellow Umbraco users, I'm currently building my first umbraco website and since I'm completely new to umbraco I've already ran into a problem which I'm sure is pretty straight-forward to do. That said, I'm by no means a beginner when it comes to building sites that run on a (open source) CMS as I've been using Joomla! since it was called Mambo. Anyway, the site I'm building is here: my site What I want to do is to have some content in the white box that changes when you mouseover/hover one of the menu items. Also that content has to stay "active" when you've clicked on a link (i.e. if you click on "Profile" I need to highlight the Profile menu item with the gray color and the white boxs content needs to be what would be related to the Profile menu item. How do I go about this? What would be the best practice when it comes to showing multiple content on a site? I've watched the video about multiple Content Place Holders, but I never really got it to work. I can't get a page to display in the NavigationPlaceHolder (the placeholder I put in the white box), but thats because the actual page is Frontpage.aspx and not WhateverIsInThenavigationPlaceHolder.aspx. If I go to the mysite.dk/WhateverIsInTheNavigationPlaceHolder.aspx it shows up fine. What have I missed here? :) Thanks in advance! If my question is not clear in some ways, please tell me and I will try to explain it better. All the best, Bo

• In WMI, can I use a join (or something similar) to acquire the IisWebServer object for a site, given

  - by Precipitous

  Given a server name and a physical path, I'd like to be able to hunt down the IISWebServer object and ApplicationPool. Website url is also an acceptable input. Our technologies are IIS 6, WMI, and access via C# or Powershell 2. I'm certain this would be easier with IIS 7 its managed API. We don't have that yet. Here's what I can do: Get a list of IIS virtual directories from IISWebVirtualDirSetting and filter (offline) for the matching physical path. $theVirtualDir = gwmi -Namespace "root/MicrosoftIISv2" ` -ComputerName $servername -authentication PacketPrivacy ` -class "IISWebVirtualDirSetting" ` | where-object {$_.Path -like $deployLocation} From the virtual directory object, I can get a name (like W3SVC/40565456/root). Given this name, I can get to other goodies, such as the IIS web server object. gwmi -Namespace "root/MicrosoftIISv2" ` -ComputerName $servername ` -authentication PacketPrivacy ` -Query "SELECT * FROM IisWebServer WHERE Name='W3SVC/40589473'" The questions, restated: 1) This is a query language. Can I join or subquery so that 1 WMI query statement gets web servers based on IISWebVirtualDir.Path? How? 2) In solving 1, you'll have to explain how to query on the Path property. Why is this an invalid query? "SELECT * FROM IISWebVirtualDirSetting WHERE Path='D:\sites\globaldominator'"
