• Getting the location from a WebClient on a HTTP 302 Redirect?

  - by Michael Stum

  I have a URL that returns a HTTP 302 redirect, and I would like to get the URL it redirects to. The problem is that System.Net.WebClient seems to actually follow it, which is bad. HttpWebRequest seems to do the same. Is there a way to make a simple HTTP Request and get back the target Location without the WebClient following it? I'm tempted to do raw socket communication as HTTP is simple enough, but the site uses HTTPS and I don't want to do the Handshaking. At the end, I don't care which class I use, I just don't want it to follow HTTP 302 Redirects :)

• How to correctly open WCF service

  - by Sergej Andrejev

  Hi there, I'm using WCF client like this... var client = new TestClient(); try { response = service.Operation(request); } finally { try { if (client.State != CommunicationState.Faulted) client.Close(); } catch (Exception) { client.Abort(); } } but from time to time I get 500 HTTP error which is the only answer I get for next 15 minutes, then everything is back to normal for 15 minutes and so on. I know there is some load balancing stuff going on service side but guys there can't find any problems with it. That's why I started wondering am I using WCF service correctly. I already made a mistake once when I was using "using" to close service connection and I'm afraid I doing something wrong again. So can anybody say whether my way of calling WCF service is correct or not in all (event the most rare) circumstances?

• FormsAuthentication.RedirectFromLoginPage reload page

  - by Dofs

  Hi, I am using the .Net memebership system, and uptil now I haven't had any real troubles with it. I now have a overlay where a user can create a profile. When the profile is created I just want to redirect to the same page, and not to the default page or the return url - which doesn't exists. I have tried to stop the FormsAuthentication.RedirectFromLoginPage response, but with no effect: FormsAuthentication.RedirectFromLoginPage(username, false); // End the redirect so it doesnt redirect to default url (front-page) Response.End(); Response.Redirect(Request.RawUrl); Does anyone have an idea to how this can be solved?

• UnknownHostException for server java

  - by nilesh

  I am not able to connect to an remote known server through Java code; the exception while connecting is java.net.NoRouteToHostException: No route to host. But strangely, I am able to connect to same server through ssh. Details: Simple Java client when tries to establish connection with Java standalone server, while conneting the exception occurs at following statement: Socket socket = new Socket(ServerIP ServerPort); The port needed is open on server so that externally request can come in. Again the following is returns false InetAddress.getByName(SERVER_IP).isReachable(1000) The Server is running on Fedora, Java 5. FYI: Java cannot resolve DNS address from AIX: UnknownHostException is almost same to my question, but somehow this is not AIX related; moreover I feel the issue to be more of Network or firewall issue. Please guide me.

• IIS 7 - floats returning with commas instead of periods

  - by cc0

  I'm having trouble reading rows with float values, because these rows return for example 12,34 instead of 12.34 as it should. I suspect this is because both my IIS and SQL server is on a Norwegian Windows Server 2008. So I went to the regional settings and customized the default decimal symbol, then restarted my servers. The output in the database now shows the period decimal symbol, but when I request it through the IIS server it comes comma separated (the IIS server is on another computer, but that also has the default decimal symbol set to period). The IIS server is IIS7 and the SQL Server is 2008 Does anyone have any idea how to fix this? Any help would be greatly appreciated.

• Django multiple generic_inline_formset in a view

  - by Can Burak Cilingir

  We have a bunch of formsets: EmailAddressInlineFormSet = generic_inlineformset_factory( EmailAddress, extra=1, exclude=["created_by","last_modified_by"]) emailaddressformset = EmailAddressInlineFormSet( instance=person, prefix="emailaddress") # [ more definitions ] and, in the view, we process them as: emailaddressformset = EmailAddressInlineFormSet( request.POST, instance=person, prefix="emailaddress") # [ more definitions ] So, nothing fancy or unordinary. The unfortunate or unordinary fact is, we have 15 of these formsets, one for email addresses, other for phone numbers etc. so the view code is ugly and not-so-manageable. What would be the most unhackish way to handle this number of formsets in a single view? At the end -i guess- I'm looking for a class or a functionality like multiple_generic_inline_formset and open to all kind of suggestions or discussions.

• Inline Form Validation in Django

  - by allanhenderson

  Newbie request that seems difficult to implement. I would like to make an entire inline formset within an admin change form compulsory.. so in my current scenario when I hit save on an Invoice form (in Admin) the inline Order form is blank. I'd like to stop people creating invoices with no orders associated. Anyone know an easy way to do that? Normal validation like (required=True) on the model field doesn't appear to work in this instance. Thanks!!

  - by cpjolicoeur

  I'm trying to write an API wrapper in ruby and am stumped on how I can call HTTParty methods from a subclass. For instance, I want the user to create a connection to the api and then be able to query results from subclasses. module ApiWrapper class Connection include HTTParty base_uri '...' def initialize( u, p ) ... end def contacts ApiWrapper::Contact end end end module ApiWrapper class Contact def all # issue httparty get request here that is created from the Connection class end end end ## The user would do this conn = ApiWrapper::Connection.new( 'username', 'password' ) contacts = conn.contacts.all

• Connecting to TFS from iPhone

  - by Andrei

  Hi. I'm building this iPhone application to connect to a secured TFS server (one that requires authentication before letting you access its web services). When I access this server in a browser, the first thing it will do is ask me for credentials (username/password) and then connect me to the TFS server if those credentials are correct. I am using web services, as I don't think there is any other way to use TFS functionality for an outside platform...without changing stuff on the TFS host machine. So my questions are: Are there any web services that can be accessed to log into the TFS server? This authentication mechanism seems to be something common among multiple websites (I have seen it in other websites). Is there a way to replicate that authentication mechanism by sending an HTTP request? Is there a way to replicate this authentication procedure in any way? Thanks!

• How to get the Facebook iFrame Tab url (including parameters) from within the app?

  - by martincarlin87

  I think there are a few similar questions that seem to suggest using app_data in the signed request (http://developers.facebook.com/docs/authentication/signed_request/) but I'm not sure if it will be possible to do what I am trying to achieve with it as I've never used it before. If I have my Facebook 'Tab' Url as follows: http://www.facebook.com/pages/PAGE_TITLE/PAGE_ID?sk=app_APP_ID What I want to do is add an extra parameter on the end as follows: &WT.mc_id=email-uk-8014 The reason for this is for tracking purposes and links will be sent out of the form http://www.facebook.com/pages/PAGE_TITLE/PAGE_ID?sk=app_APP_ID&WT.mc_id=email-uk-8014 and the extra parameter will allow us to track the campaign id. As you can see I have no way of knowing the value of the parameter beforehand as it depends on the link clicked by the user so is it possible to somehow get the value of the WT.mc_id parameter inside my iframe app?

• Django: accessing session variables from within a template?

  - by AP257

  Hi all If I set a session variable in Django, like: request.session["name"] = "name" Is there a way I can access it from within a template, or do I have to retrieve it from within a view, and then pass it to a template? Asking because I have around 10 little session variables that I'd like to access within a template, and passing all 10 from the view to the template could get a bit messy. (I have to use session variables because it's a HttpResponseRedirect, but storing the variables in a database is overkill for my purposes.) So - any way to grab session variables directly within a template?

• How to avoid timestamp issue in a long query?

  - by pingi

  Hi, I have the following 2 tables: items: id int primary key bla text events: id_items int num int when timestamp without time zone ble text composite primary key: id_items, num and want to select to each item the most recent event (the newest 'when'). I wrote an request, but I don't know if it could be written more efficiently. Also on PostgreSQL there is a issue with comparing Timestamp objects: 2010-05-08T10:00:00.123 == 2010-05-08T10:00:00.321 so I select with 'MAX(num)' Any thoughts how to make it better? Thanks. SELECT i.*, ea.* FROM items AS i JOIN ( SELECT t.s AS t_s, t.c AS t_c, max(e.num) AS o FROM events AS e JOIN ( SELECT DISTINCT id_item AS s, MAX(when) AS c FROM events GROUP BY s ORDER BY c ) AS t ON t.s = e.id_item AND e.when = t.c GROUP BY t.s, t.c ) AS tt ON tt.t_s = i.id JOIN events AS ea ON ea.id_item = tt.t_s AND ea.cas = tt.t_c AND ea.num = tt.o;

• MySQL 5.1 implicit cast from now() to a date field

  - by Savageman

  Hello, I have an issue with MySQL 5.1. A datetime data type isn't implicitly casted to match a date column. SELECT * FROM my_table WHERE my_date_field = NOW() This request doesn't return any rows using MySQL 5.1, but works well with version 5.0. If we use CURDATE() instead of NOW() it works both in MySQL 5.0 and MySQL 5.1. If the cast is explicit (CAST(NOW() AS DATE)), it also works both in MySQL 5.0 and MySQL 5.1. The problem only appears with implicit cast from datetime to date. Doesn't anyone already encountered this issue or has a clue about how to solve this problem? I know it's not the best to use NOW() instead of CURTIME(), but this isn't the question here. It is currently used in an application and the purpose is to avoid rewriting everything. Thanks!

• Can I close and reopen a socket?

  - by Roman

  I learned an example of usage of sockets. In this example a client sends a request to a server to open a socket and then the server (listening to a specific port) opens a socket and everything is fine, socket is "opened" from both sides (client and server). But it is still not clear to me how flexible is this stuff. For example, is it possible for the client to close an opened (from both ends) socket and to reopen it again (under condition that the server keeps the socket opened). Is it possible for the server to "know" that a socket was closed on the client side? Is it possible for the client to know that a socket was closed on the server side?

• accessing pdf via https URL

  - by Paul

  I send out a newsletter email containing URLs to a https website that then redirects to a pdf document. On first invocation of a URL the user is prompted with the typical https browser "security alert" popup, on selecting "Yes" the display of the PDF fails. The HTTP Header on the failed response is: HTTP/1.1 200 OK Server: ECS/HTTP-Server Date: Tue, 16 Mar 2010 15:57:26 GMT Content-type: application/pdf Content-language: en-US Set-cookie: JSESSIONID=0000r111cRz1Vc-PtCJg8Cdu4eR:-1; Path=/ Expires: Thu, 01 Dec 1994 16:00:00 GMT Cache-control: no-cache="set-cookie, set-cookie2" Connection: close Subsequent invocations of the URL successfully opens the PDF (at this point we have the session id cookie set by the initial failed request). The HTTP Header on the successful response is: HTTP/1.1 200 OK Server: ECS/HTTP-Server Date: Tue, 16 Mar 2010 16:53:03 GMT Content-type: application/pdf Content-language: en-US Connection: close The email client is Lotus Notes 6.5 which launches an IE6 browser Any ideas?

• How do I fire an asynchronous call in asp classic and ignore the response?

  - by Hexate

  Here's the gist: I have a call I want to make in asp, and I do not care about the response. I just want to fire the call and I do not want the page to wait for the response. According to the documentation, it should look something like this: dim xmlhttp : set xmlhttp = Server.CreateObject("MSXML2.ServerXMLHTTP") xmlhttp.Open "POST", url, true '' setting the 'asynchronous' option to 'true' xmlhttp.setRequestHeader "Content-Type", "application/soap+xml; charset=utf-8" xmlhttp.setRequestHeader "Content-Length", Len(XMLData) xmlhttp.send XMLData This works peachy when calling synchronously, but when I flip the ansynchronous option to 'true', nothing fires. What I can gather from the internet is that users do something like the following: While xmlhttp.readyState <> 4 xmlhttp.waitForResponse 1000 Wend Am I crazy in that this does not really seem like an asynchrous call anymore though if you are waiting for a response? putting the line xmlhttp.waitForResponse 1 right after the send will cause the request to fire, but again, I don't want to wait a second. Any thoughts?

• Facebook - using an external flash application to connect via PHP

  - by Anonymous

  So, I have this application that needs to connect to facebook. It uses php for all of its data access, in older examples of the facebook API, i see people get the UID, and sessionkey from the iframe page, then send them to php and run a function called $facebook-setUser($UID, $sessionKey). This is how the majority of the tutorials online are doing it. That would be great, except the newest facebook API doesn't have any function like that. I have been scouring the web for 2 hours and have found nothing relating to the disappearance of this seemingly critical function. So, I have a flash application that needs to authenticate via a stateless php resource. I would love it if my PHP code could be completely uncaring if the request originated from flash, or iphone, or another application altogether-it should just need userId and and sessionKey. Is this still possible? Thank you in advance for your help! :)

• Question about tracking user in a map application using cellid

  - by subh

  I am trying to understand the concept of cellid (http://www.opencellid.org/api) As per that, if we send a request http://www.opencellid.org/cell/get?key=myapikey&mnc=1&mcc=2&lac=200&cellid=234 it will respond with the latitude and longitude. I was wondering if this can be used from within a google map application for tracking a user or it needs to be used from within a mobile device? If it can be used from within a web app, what parameters should it use for mcc: mobile country code (decimal) mnc: mobile network code (decimal) lac: locale area code (decimal) cellid: value of the cell id E.g., will it work if we know the cell number of the person(e.g., 281 222 6700)

• Debugging ASP.NET on a built-in web server suddenly stops

  - by Anton Gogolev

  I have Windows Server 2008 (64-bit), VS 2008 with its built-in webserver and an ASP.NET MVC 1.0 webapp. All I'm trying to do is to debug said app. I have a bunch of breakpoints, but they behave in a very strange way. When I fist start a debugging session with F5 and hit a breakpoint, the debugger stops just fine. However, after serveral F10s/F11s debugging suddenly "stops" (no exceptions at that time), but neither VS detaches from browsers' process, nor webapp execution stops: Visual Studio stays attached, and web request continues executing as usual. I tried various browsers (Chrome, Firefox, IE), but to no avail. What do I do to solve this? It really drives me insane.

• Why are $_POST variables getting escaped in PHP?

  - by George Edison

  When my PHP script receives data from an AJAX POST request, the $_POST variables are escaped. The really strange thing is that this only happens on my production server (running PHP 5.2.12 on Linux) and not on my local server (running PHP 5.3.1 on Windows). Here is the AJAX code: var pageRequest = false; if(window.XMLHttpRequest) pageRequest = new XMLHttpRequest(); else if(window.ActiveXObject) pageRequest = new ActiveXObject("Microsoft.XMLHTTP"); pageRequest.onreadystatechange = function() { } var q_str = 'data=' + " ' "; pageRequest.open('POST','unnamed_page.php',true); pageRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); pageRequest.setRequestHeader("Content-length", q_str.length); pageRequest.setRequestHeader("Connection", "close"); pageRequest.send(q_str); Is there any reason this is happening? And how should I fix this so that it works on both servers?
