• identify accounts using zend-openid [HELP]

  - by tawfekov

  Hi! , i had successfully implemented simple open ID authentication with the [gmail , yahoo , myopenid, aol and many others ] exactly as stackoverflow do but i had a problem with identifying accounts for example 'openid_ns' => string 'http://specs.openid.net/auth/2.0' (length=32) 'openid_mode' => string 'id_res' (length=6) 'openid_op_endpoint' => string 'https://www.google.com/accounts/o8/ud' (length=37) 'openid_response_nonce' => string '2010-05-02T06:35:40Z9YIASispxMvKpw' (length=34) 'openid_return_to' => string 'http://dev.local/download/index/gettingback' (length=43) 'openid_assoc_handle' => string 'AOQobUf_2jrRKQ4YZoqBvq5-O9sfkkng9UFxoE9SEBlgWqJv7Sq_FYgD7rEXiLLXhnjCghvf' (length=72) 'openid_signed' => string 'op_endpoint,claimed_id,identity,return_to,response_nonce,assoc_handle' (length=69) 'openid_sig' => string 'knieEHpvOc/Rxu1bkUdjeE9YbbFX3lqZDOQFxLFdau0=' (length=44) 'openid_identity' => string 'https://www.google.com/accounts/o8/id?id=AItOawk0NAa51T3xWy-oympGpxFj5CftFsmjZpY' (length=80) 'openid_claimed_id' => string 'https://www.google.com/accounts/o8/id?id=AItOawk0NAa51T3xWy-oympGpxFj5CftFsmjZpY' (length=80) i thought that openid_claimed_id or openid_identity is identical for every account but after some testing turns out the claimed id is changeable by the users them self in yahoo and randomly changing in case of gmail FYI am using zend openid with a bit modification on consumer class and i can't use SERG [Simple Refistration Extension] cuz currently it uses openid v1 specification :( i hadn't read the specification of openid so if any body know please help me to how to identify openid accounts to know if this account has signed in before or not

• Save Bitmap image in a location in C#

  - by acadia

  Hello, I have this function to store the bmp image in a desired location as shown below My question is, how do I save the image in C:\temp folder by default, instead of opening the filedialog box? I want to specify sd.fileName=picname+".bmp" and store it in c:\temp by default. I tried to specify Thanks for your help in advance. I tried to public static bool SaveDIBAs( string picname, IntPtr bminfo, IntPtr pixdat ) { SaveFileDialog sd = new SaveFileDialog(); sd.FileName = picname; sd.Title = "Save bitmap as..."; sd.Filter = "Bitmap file (*.bmp)|*.bmp|TIFF file (*.tif)|*.tif|JPEG file (*.jpg)|*.jpg|PNG file (*.png)|*.png|GIF file (*.gif)|*.gif|All files (*.*)|*.*"; sd.FilterIndex = 1; if( sd.ShowDialog() != DialogResult.OK ) return false; Guid clsid; if( !

• How to programmatically create a node in Drupal 8?

  - by chapka

  I'm designing a new module in Drupal 8. It's a long-term project that won't be going public for a few months at least, so I'm using it as a way to figure out what's new. In this module, I want to be able to programmatically create nodes. In Drupal 7, I would do this by creating the object, then calling "node_submit" and "node_save". These functions no longer exist in Drupal 8. Instead, according to the documentation, "Modules and scripts may programmatically submit nodes using the usual form API pattern." I'm at a loss. What does this mean? I've used Form API to create forms in Drupal 7, but I don't get what the docs are saying here. What I'm looking to do is programmatically create at least one and possibly multiple new nodes, based on information not taken directly from a user-presented form. I need to be able to: 1) Specify the content type 2) Specify the URL path 3) Set any other necessary variables that would previously have been handled by the now-obsolete node_object_prepare() 4) Commit the new node object I would prefer to be able to do this in an independent, highly abstracted function not tied to a specific block or form. So what am I missing?

• Open-sourcing a web site with active users?

  - by Lars Yencken

  I currently run several research-related web-sites with active users, and these sites use some personally identifying information about these users (their email address, IP address, and query history). Ideally I'd release the code to these sites as open source, so that other people could easily run similar sites, and more importantly scrutinise and replicate my work, but I haven't been comfortable doing so, since I'm unsure of the security implications. For example, I wouldn't want my users' details to be accessed or distributed by a third party who found some flaw in my site, something which might be easy to do with full source access. I've tried going half-way by refactoring the (Django) site into more independent modules, and releasing those, but this is very time consuming, and in practice I've never gotten around to releasing enough that a third party can replicate the site(s) easily. I also feel that maybe I'm kidding myself, and that this process is really no different to releasing the full source. What would you recommend in cases like this? Would you open-source the site and take the risk? As an alternative, would you advertise the source as "available upon request" to other researchers, so that you at least know who has the code? Or would you just apologise to them and keep it closed in order to protect users?

• Is there a definitive reference document for Ruby syntax?

  - by JSW

  I'm searching for a definitive document on Ruby syntax. I know about the definitive documents for the core API and standard library, but what about the syntax itself? For instance, such a document should cover: reserved words, string literals syntax, naming rules for variables/classes/modules, all the conditional statements and their permutations, and so forth. I know there are many books and tutorials, yes, but every one of them is essentially a tutorial, each one having a range of different depth and focus. They will all, by necessity of brevity and narrative flow, omit certain details of the language that the author deems insignificant. For instance, did you know that you can use a case statement without an initial case value, and it will then execute the first true when clause? Any given Ruby book or tutorial may or may not cover that particular lesser-known functionality of the case syntax. It's not discussed in the section in "Programming Ruby" about case statements. But that is just one small example. So far the best documentation I've found is the rubyspec project, which appears to be an attempt to write a complete test suite for the language. That's not bad, but it's a bit hard to use from a practical standpoint as a developer working on my own projects. Am I just missing something or is there really no definitive readable document defining the whole of Ruby syntax?

• Entity Framework POCO objects

  - by Dan

  I'm struggling with understanding Entity Framework and POCO objects. Here's what I'm trying to achieve. 1) Separate the DAL from the Business Layer by having my business layer use an interface to my DAL. Maybe use Unity to create my context. 2) Use Entity Framework inside my DAL. I have a Domain model with objects that reside in my business layer. I also have a database full of tables that doesn't really represent my domain model. I setup Entity Framework and generated POCO objects by using the ADO.NET POCO Generator extension. This gave me an object for each table in my database. Now I want to be able to say context.GetAll<User>(); and have it return a list of my User objects. The User object is in my business layer. Is that possible? Does that make sense or am I totally off and should start over? I'm guessing I need to use the repository pattern to achieve this, but I'm not sure. Can anyone help?

• Why does this Haskell code produce the "infinite type" error?

  - by Charlie Flowers

  I am new to Haskell and facing a "cannot construct infinite type" error that I cannot make sense of. In fact, beyond that, I have not been able to find a good explanation of what this error even means, so if you could go beyond my basic question and explain the "infinite type" error, I'd really appreciate it. Here's the code: intersperse :: a -> [[a]] -> [a] -- intersperse '*' ["foo","bar","baz","quux"] -- should produce the following: -- "foo*bar*baz*quux" -- intersperse -99 [ [1,2,3],[4,5,6],[7,8,9]] -- should produce the following: -- [1,2,3,-99,4,5,6,-99,7,8,9] intersperse _ [] = [] intersperse _ [x] = x intersperse s (x:y:xs) = x:s:y:intersperse s xs And here's the error trying to load it into the interpreter: Prelude :load ./chapter.3.ending.real.world.haskell.exercises.hs [1 of 1] Compiling Main ( chapter.3.ending.real.world.haskell.exercises.hs, interpreted ) chapter.3.ending.real.world.haskell.exercises.hs:147:0: Occurs check: cannot construct the infinite type: a = [a] When generalising the type(s) for `intersperse' Failed, modules loaded: none. Thanks. EDIT: Thanks to the responses, I have corrected the code and I also have a general guideline for dealing with the "infinite type" error in Haskell: Corrected code intersperse _ [] = [] intersperse _ [x] = x intersperse s (x:xs) = x ++ s:intersperse s xs What the problem was: My type signature states that the second parameter to intersperse is a list of lists. Therefore, when I pattern matched against "s (x:y:xs)", x and y became lists. And yet I was treating x and y as elements, not lists. Guideline for dealing with the "infinite type" error: Most of the time, when you get this error, you have forgotten the types of the various variables you're dealing with, and you have attempted to use a variable as if it were some other type than what it is. Look carefully at what type everything is versus how you're using it, and this will usually uncover the problem.

• Durandal Google Maps not showing properly

  - by user1891037

  Trying to show Google Maps using the Durandal. I'm now simply working with Durandal HTML Starter Kit so the other modules and all engine works properly. The thing is when I added the Google Map it doesn't fit the div size (the big part of div is just grey). As I understand, the problem is causing because Google Maps added before page is completely loaded. But I can't figure out how can I hook on page load event. Here is the module code: define(['knockout', 'gmaps'], function (ko, gmaps) { return { displayName: 'Google Maps', myMap: ko.observable({ lat: ko.observable(32), lng: ko.observable(10)}), activate: function () { console.log('activate'); ko.bindingHandlers.map = { init: function (element, valueAccessor, allBindingsAccessor, viewModel) { console.log('init'); var mapObj = ko.utils.unwrapObservable(valueAccessor()); var latLng = new gmaps.LatLng( ko.utils.unwrapObservable(mapObj.lat), ko.utils.unwrapObservable(mapObj.lng)); var mapOptions = { center: latLng, zoom: 5, mapTypeId: gmaps.MapTypeId.ROADMAP}; mapObj.googleMap = new gmaps.Map(element, mapOptions); } } }, attached: function() { console.log('attached'); }, compositionComplete: function() { console.log('compositionComplete'); } }; }); And a very simple HTML code: <section> <div id="gmap-canvas" data-bind="map:myMap"></div> </section> I'm loading Google Maps with async plug-in in my shell.js. It works fine. Screenshot with trouble here - http://clip2net.com/s/ibswAa P.S. div size is defined in .CSS file. P.S. I tried to use getElementById approach provided here and it's work great if placed in compositionComplete block. But when I tried to move my bindings to this block nothing happens at all. Thanks!

• Save PowerPoint slides as images

  - by nihi_l_ist

  I want to save some presentation file as images into some directory and use the code: OpenFileDialog o = new OpenFileDialog(); o.ShowDialog(); if (o.FileName != null) { ApplicationClass pptApplication = new ApplicationClass(); Presentation pptPresentation = pptApplication.Presentations.Open(o.FileName, MsoTriState.msoFalse, MsoTriState.msoFalse, MsoTriState.msoFalse); FolderBrowserDialog fb = new FolderBrowserDialog(); fb.ShowDialog(); for (int i = 0; i < pptPresentation.Slides.Count; i++) { pptPresentation.Slides[i].Export(fb.SelectedPath + "Slide" + (i + 1) + ".jpg", "jpg", 320, 240); } } use namespaces: using Microsoft.Office.Core; using Microsoft.Office.Interop.PowerPoint; But i get the following error: 'Microsoft.Office.Interop.PowerPoint.ApplicationClass' does not contain a definition for 'Presentations' and no extension method 'Presentations' accepting a first argument of type 'Microsoft.Office.Interop.PowerPoint.ApplicationClass' could be found (are you missing a using directive or an assembly reference?) Tho it seems that it has property called Presentations.. What am i doing incorrectly?

• Getting batch_action functionality in Symfony 1.0

  - by Alex Ciminian

  I'm currently working on a web app written in Symfony. I'm supposed to add an "export to CSV" feature in the backend/administration part of the app for some modules. In the list view, there should be an "Export" button which should provide the user with a csv file of the elements that are displayed (considering filtering criteria). I've created a method in the actions class of the module that takes a comma separated list of ids and generates the CSV, but I'm not really sure how to add the link to it in the view. The problem is that the view doesn't exist anywhere, it's generated on the fly from the data in the generator.yml configuration file. I've posted the relevant part of the file below. I'm new to Symfony, so any help would be appreciated :). Thanks, Alex Update list: display: [id, =name, indemn, _status, _participants, _approved_, created_at] title: Lista actiuni object_actions: _edit: ~ _delete: ~ actions: _create: ~ export_csv: name: Export to CSV action: CSVExport params: id=csvActionSubmit filters: [name, county_id, _status_filter, activity_id] fields: id: name: Nr. crt. ... Thanks to your advice, I've managed to add a button that is linked to my action. The problem is that I also need to send some parameters to the action, because I may not want all the elements - filters may have been used. Unfortunately, the project is using Symfony 1.0, which doesn't support batch_actions. Currently, I'm working around this with Javascript (I parse the DOM to get the numeric ids (from the display table) and then build the link for the button. I really think there could be a better way for this.

• Apache redirection problem!!!!

  - by vikas

  Hi guys, I am setting up a pre-built website built in php. The site was actually hosted on the linux server. Now I am trying to set it up on a Window machine with WAMP server. In this website almost every page request passes through a particular file called redirect(which is basically a php file without extension). Now the problem is that when I inspected the configuration(httpd.conf, apache.conf,.htaccess, vhost.conf etc) of the apache server on the linux machine, I nowhere found the redirect rules for doing so. Neither mod_rewrite nor mod_alias rules for this redirection were found there. But is still redirects the request properly. I also noticed that Zend Framework library is there in the exact same directory where the redirect file is. This library is included in the include_path in php.ini. However, the web site is still not developed using Zend MVC and I have seen NO proof of ZEND being used there. So I am really confused how this redirection is working there? I am unable to set up this on window machine without rewrite rules of mod_rewrite or mod_alias. Do you guys know any alternative of both the said modules for redirection? I know the site is really weird, but i have to set it up. :) Thanks in advance for your help.

• Using Maven for maintaining product documentation

  - by Waldheinz

  We are using Maven for building a Java server-style application. It consists of several modules (in a single Maven "reactor") which can be plugged together to generate a final product (essentially a .jar) with the features enabled that the customer needs. All the internals are documented using JavaDoc and all, but that's not what you can give to the customer to find out how to get the thing running. Currently we have an OpenOffice document which serves as end-user documentation. I'd like to integrate this documentation into the Maven build process where each module's documentation is maintained (hand-edited) together with the Module's sources and the final document can reference the required Module documentation sections, add some friendly foreword and, if possible at all, can reference into the JavaDocs. Ultimately, the document should be output as a PDF. Is there any experience on Maven plugins can help with this? Is DocBook the right tool? Maybe Latex? Or something completely different? A sound "stick with OpenOffice and some text blocks" could be an answer, too.

• Ninject: How do I inject into a class library ?

  - by DennyDotNet

  To start I'm using Ninject 1.5. I have two projects: Web project and a Class library. My DI configuration is within the Web project. Within my class library I have the following defined: public interface ICacheService<T> { string Identifier { get; } T Get(); void Set( T objectToCache, TimeSpan timeSpan ); bool Exists(); } And then a concrete class called CategoryCacheService. In my web project I bind the two: Bind( typeof( ICacheService<List<Category>> ) ).To( typeof(CategoryCacheService)).Using<SingletonBehavior>(); In my class library I have extension methods for the HtmlHelper class, for example: public static class Category { [Inject] public static ICacheService Categories { get; set; } public static string RenderCategories(this HtmlHelper htmlHelper) { var c = Categories.Get(); return string.Join(", ", c.Select(s = s.Name).ToArray()); } } I've been told that you cannot inject into static properties, instead I should use Kernel.Get<() - However... Since the code above is in a class library I don't have access to the Kernel. How can I get the Kernel from this point or is there a better way of doing this? Thanks!

• iPhone: Helpful Classes or extended Subclasses which should have been in the SDK

  - by disp

  This is more a community sharing post than a real question. In my iPhone OS projects I'm always importing a helper class with helpful methods which I can use for about every project. So I thought it might be a good idea, if everyone shares some of their favorite methods, which should have been in everyones toolcase. I'll start with an extension of the NSString class, so I can make strings with dates on the fly providing format and locale. Maybe someone can find some need in this. @implementation NSString (DateHelper) +(NSString *) stringWithDate:(NSDate*)date withFormat:(NSString *)format withLocaleIdent:(NSString*)localeString{ NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; //For example @"de-DE", or @"en-US" NSLocale *locale = [[NSLocale alloc] initWithLocaleIdentifier:localeString]; [dateFormatter setLocale:locale]; // For example @"HH:mm" [dateFormatter setDateFormat:format]; NSString *string = [dateFormatter stringFromDate:date]; [dateFormatter release]; [locale release]; return string; } @end I'd love to see some of your tools.

• How do I get Firefox to launch Visio when I click on a linked .vsd file?

  - by Dean

  On our intranet site, we have various MS Office documents linked. When I click on a Word, Excel or PowerPoint file, Firefox gives me the option to Open, Save or Cancel. When I click on Open, the appropriate app is launched and the file is loaded. This is perfect. But for some reason, when I click on a linked Visio file, I only get the option to Save, which is inconvenient. I know that Firefox knows the linked file is a Visio file because it tells me so in the dialog box: "You have chosen to open example.vsd which is a: Microsoft Visio Drawing". How can I make Firefox launch Visio when I click on a linked Visio file? Update: Firefox is not launching Visio when I click on a linked Visio file because the web server does not identify the content-type correctly. It identifies the Visio file as application/octet-stream instead of application/x-visio. (Thanks Grant Wagner.) This explains why it doesn't work. And in my case, I may be able to get the Apache config file changed, but this is not certain. However, I would love to know if there is a way to configure Firefox itself to launch Visio based on some other criteria, like file name extension. This way I can open Visio files even if I don't have access to the Apache configuration.

• Some images fails to load on Windows Server 2008

  - by Guffa

  I have an application running on a Windows Server 2008, that is processing uploaded images. Currently it successfully processes about 8000 images per day, creating 11 different sizes of each image. The problem that I have is that sometimes the application fails to load some images, I get the error "System.Runtime.InteropServices.ExternalException: A generic error occurred in GDI+.". The upload only accepts files with a JPEG extension (jpg/jpeg/jpe) or with a JPEG MIME type, and from what I can tell those images are really JPEG images. If I look at the image file in windows explorer on the server, it can successfully extract the thumbnail from the file, but if I try to open it, I get the error message "This is not a valid bitmap file, or it's format is not currently supported." from Paint. If I copy the image to my own computer, running Windows 7, there is no problem opening the image. It works in Paint, Windows Photo Viewer, Adobe Bridge, and Photoshop. If I try to load the image using Image.FromStream the same way as in the application running on the server, it loads just fine. (I have copied the file back to the server, and it still doesn't work, so there is nothing in the copying process that changes it.) When I look at the image information in Bridge, I see that the images are created using Picasa 3.0, but other than that I can't see anything special about them. I haven't yet found anyone having the same problem, or any known problems like this with the Picasa application. Has anyone had any similar problem, or know if there is something special about images created using Picasa? Is there any image codec that needs installing on the server to handle all kinds of JPEG images?

• A beginner question on passthru() function in PHP

  - by Robert

  Hi all, I've used the following code to do an XSLT translation in PHP and save the result SVG file into a sub folder: $command = $java . $saxon . $target2 . ' ' . $xsl2.' '.$param; ob_start(); passthru($command, $result); $content_grabbed=ob_get_contents(); ob_end_clean(); $info = pathinfo($_FILES['file']['name']); $file_name= basename($_FILES['file']['name'],'.'.$info['extension']); $myFile = "images/convert/".$file_name."_".$_POST["mydropdown"].".svg"; $fh = fopen($myFile, 'w') or die("can't open file"); fwrite($fh, $content_grabbed); fclose($fh); It does a very simple SVG to SVG transformation, and created the resulting SVG file. the $command is just a simple java -jar saxon.jar input.xml stylesheet java command. The current situation is ,the file gets created perfectly, however, the error gets shown in browser, probably because I inserted the "ob_start" before passthru() command. I am thinking of making use of an argument that comes with the saxon.jar, that is "-o output_file_name". Because the final purpose is not to display the resulting SVG to the browser, but instead creating an SVG file ,and provide the link to the user for downloading. Are there any better ways to handle this problem, I am still thinking about how to get rid of the result that gets shown in the browser that is sent by the "passthru()". Thanks in advance for suggestions!

• Rails: Obfuscating Image URLs on Amazon S3? (security concern)

  - by neezer

  To make a long explanation short, suffice it to say that my Rails app allows users to upload images to the app that they will want to keep in the app (meaning, no hotlinking). So I'm trying to come up with a way to obfuscate the image URLs so that the address of the image depends on whether or not that user is logged in to the site, so if anyone tried hotlinking to the image, they would get a 401 access denied error. I was thinking that if I could route the request through a controller, I could re-use a lot of the authorization I've already built into my app, but I'm stuck there. What I'd like is for my images to be accessible through a URL to one of my controllers, like: http://railsapp.com/images/obfuscated?member_id=1234&pic_id=7890 If the user where to right-click on the image displayed on the website and select "Copy Address", then past it in, it would be the SAME url (as in, wouldn't betray where the image is actually hosted). The actual image would be living on a URL like this: http://s3.amazonaws.com/s3username/assets/member_id/pic_id.extension Is this possible to accomplish? Perhaps using Rails' render method? Or something else? I know it's possible for PHP to return the correct headers to make the browser think it's an image, but I don't know how to do this in Rails... UPDATE: I want all users of the app to be able to view the images if and ONLY if they are currently logged on to the site. If the user does not have a currently active session on the site, accessing the images directly should yield a generic image, or an error message.

• XML File as Excel file.

  - by FrustratedWithFormsDesigner

  I have a number of reports that I run against my database that need to eventually go to the end-users as Excel spreadsheets. Initially, I was creating text reports, but the steps to convert the text to a spreadsheet were a bit cumbersome. There were too many steps to import text to the spreadsheet, and multi-line text rows were imported as individual rows in Excel (which was incorrect). Currently, I am generating simple XML saving the file with an ".xls" extension. This works better, but there is still the problem of Excel prompting the user with an XML import dialogue every time they open the file, and then having to save a new file if they add notes or change the layout to the file (which they almost certainly will be doing). Sample "xls" file: <?xml version="1.0" standalone="yes"?> <report_rows> <row> <NAME>Test Data</NAME> <COUNT>345</COUNT> </row> <!-- many more row elements... --> </report_rows> Is there any way to add markup to the file to hint to Excel how it should import and handle the file? Ideally, the end user should be able to open and save the file like any othe spreadsheet they create directly from Excel. Is this even possible? UPDATE: We are running Office 2003 here. UPDATE: The XML is generated from a sqlplus script, no option to use C#/.NET here.

• How to structure this Symfony web project?

  - by James William

  I am new to Symfony and am not sure how to best structure my web project. The solution must accommodate 3 use cases: Public access to www.mydomain.com for general use Member only access to member.mydomain.com Administrator access to admin.mydomain.com All three virtual hosts point to the Symfony /web directory Questions: Is this 3 separate applications in my Symfony project (e.g. "frontend", "backend" and "admin" or "public", "member", "admin")? Is this a good approach if there is to be some duplicate code (e.g. generating a member list would be common across all 3 applications, but presented differently)? How would I route to the various applications based on the subdomain when a user accesses *.mydomain.com? Where in Symfony should this routing logic be placed? Or, is this one application with modules for each of the above use cases? EDIT: I do not have access to httpd.conf in apache to specify a default page for virtual hosts. I can only specify a directory for each subdomain using the hostin provider's cPanel.

• JSR-299 (CDI) configuration at runtime

  - by nsn

  I need to configure different @Alternatives, @Decorators and @Injectors for different runtime environments (think testing, staging and production servers). Right now I use maven to create three wars, and the only difference between those wars are in the beans.xml files. Is there a better way to do this? I do have @Alternative @Stereotypes for the different environments, but even then I need to alter beans.xml, and they don't work for @Decorators (or do they?) Is it somehow possible to instruct CDI to ignore the values in beans.xml and use a custom configuration source? Because then I could for example read a system property or other environment variable. The application exclusively runs in containers that use Weld, so a weld-specific solution would be ok. I already tried to google this but can't seem to find good search terms, and I asked the Weld-Users-Forums, but to no avail. Someone over there suggested to write my own custom extension, but I can't find any API to actually change the container configuration at runtime. I think it would be possible to have some sort of @ApplicationScoped configuration bean and inject that into all @Decorators which could then decide themselves whether they should be active or not and then in order to configure @Alternatives write @Produces methods for every interface with multiple implementations and inject the config bean there too. But this seems to me like a lot of unnecessary work to essentially duplicate functionality already present in CDI?

• How to catch an expected (and intended) 302 Ajax response?

  - by Anthony

  So, if you look back at my previous question about Exchange Autodiscover, you'll see that the easiet way to get the autodiscover URL is to send a non-secure, non-authenticated GET request to the server, ala: http://autodiscover.exchangeserver.org/autodiscover/autodiscover.xml The server will respond with a 302 redirect with the correct url in the Location header. I'm trying out something really simple at first with a Chrome extension, where I have: if (req.readyState==4 && req.status==302) { return req.getResponseHeader("Location"); } With another ajax call set up with the full XML Post and the user credentials, But instead Chrome hangs at this point, and a look at the developer panel shows that it is not returning back the response but instead is acting like no response was given, meanwhile showing a Uncaught Error: NETWORK_ERR: XMLHttpRequest Exception 101 in the error log. The way I see it, refering to the exact response status is about the same as "catching" it, but I'm not sure if the problem is with Chrome/WebKit or if this is how XHR requests always handle redirects. I'm not sure how to catch this so that I can get still get the headers from the response. Or would it be possible to set up a secondary XHR such that when it gets the 302, it sends a totally different request? Quick Update I just changed it so that it doesn't check the response code: if (req.readyState==4) { return req.getResponseHeader("Location"); } and instead when I alert out the value it's null. and there is still the same error and no response in the dev console. SO it seems like it either doesn't track 302 responses as responses, or something happens after that wipes that response out?
