It seems to me that most of what can be accomplished with HttpWebRequest/Response can also be accomplished with the WebClient class. I read somewhere that WebClient is a high-level wrapper for WebRequest/Response. So far, I can't see anything that can be accomplished with HttpWebRequest/Response that can not be accomplished with WebClien...
ok. I know about the WebRequest and the WebResponse objects. The problem is that i do not really want to get the source code of the webpage, i only want to check to see if the link exists or not. The thing is, if i use the GetResponse method, it goes an pull the entire soource code of the site. i am creating a broken link checker wit...
Hi, In a controller action, I am manually sending a form to a remote URL using WebRequest. I successfully receive a WebResponse containing an html page to display. I would like to "paste" this response as the Response (of type HttpResponseBase) of the action. An action normally returns an ActionResult, so how do I conclude my controller...
I'm trying to write out to the response stream - but it is failing, it is corrupting the data somehow... I want to be able to write a stream stored somewhere else to the HttpWebResponse so I can't use 'WriteFile' for this, plus I want to do this for several MIME types but it fails for all of them - mp3, pdf etc... public void ProcessR...
OK. I just want to know if this can be done. I'm using C# asp.net language. I want to send a structure to a webserver from a webpage (much like you you can pass a structure to a function). The server would act on the data found in the structure, and then return back the structure (with its contents modified) to the "client" webpage....
I am returning a stream in some response setting the appropriate content-type header. The behavior i'm looking for is this: If the browser is able to render content of the given content-type then it should display it in the browser window. If the browser doesn't know how to render the content then it should display the saveas dialog wh...
Hello, I write a program wich download web pages. It works fine for most of web pages but i have found some pages where it doesn't work. These pages contains 0x00 characters. I'm able to read page content until this character, but not the content after. I use this part of code to read the response : IAsyncResult ar = null; HttpWebRe...
Whats the difference between these two properties? To put into context, I am determining if a redirect occurs if our ResponseUri != RequestUri. While a redirect occurs regardless the url http://adage.com/adages/article?article%5Fid=140560 will provide a different ResponseUri (http://adage.com/adages/post.php) than the Address (http://a...
Hi, Q1 - Is this a bug in .net, or is the webserver I'm using for testing ( Mongoose ) not server up the header field Last-Modified in the format it should? So in C# VS2008 if I make the call: response = (HttpWebResponse)request.GetResponse(); Console.Out.WriteLine(" - LM = " + response.LastModified); I get: ProtocolViolationExceptio...
I can't guess who is better HttpWebRequest or webclient are you suggest me who is better for performance ...
Hi All, Have been trying to write a program in C# that downloads a file using multiple segments at once like most download managers, and I've run into the issue that the files downloaded are corrupted. E.g. I download a video and it plays for 2 seconds then WMP says it's unplayable. I hexedited the downloaded file and it appears there ...
Hi, How to let Httpwebresponse ignore the 404 error and continue with it? It's easier than looking for exceptions in input as it is very rare when this happens. ...
Hi, Background - I'm trying to stream an existing webpage to a separate web application, using HttpWebRequest/HttpWebResponse in C#. One issue I'm striking is that I'm trying to set the file upload request content-length using the file download's content-length, HOWEVER the issue seems to be when the source webpage is on a webserver fo...
There is a local service from which I need to consume a generated XML Document Stream. Though the end point is not a REST service per se. I wanted to be sure the method I've outlined below is the most efficient way of getting the response returned into an XDocument. Uri requestUri = null; Uri.TryCreate(String.Format(SearchAddress, filte...
Hi, I have the following problem. I contact an address which I know employs a 301 redirect. using HttpWebRequest loHttp = (HttpWebRequest)WebRequest.Create(lcUrl); and loHttp.AllowAutoRedirect = false; so that I am not redirected. Now I get the header of the response in order to identify the new url. using loWebResponse.GetResponseHe...
I'm trying to figure out how this works exactly. HttpWebRequest has a method BeginGetResponse which accepts as a parameter a ResponseCallback. Firstly, is this callback called immediately (in a new thread) or once it receives a response back from the server? Or is it the job of EndGetResponse to wait for the response? Secondly, once yo...
Jon Skeet made a comment (via Twitter) on my SOApiDotNet code (a .NET library for the pre-alpha Stack Overflow API): @maximz2005 One thing I've noticed just from browsing the source quickly: you don't disposed (sic) of WebResponses. "using" statements FTW. He indicates that I need to wrap these Web sessions in "using" stateme...
Hi, I want to simulate the behaviour of the WebTestRequest class (in Visual Studio's Test Tools framework) where it can invoke dependent requests based on resources that are referred to in the response that is obtained from the original request. For example, if I issue a web request and get the response by doing this: string url = "ht...

Hello, I'm trying to establish a connection to a server that sends 401 Authentication Error for all my requests along with the normal html response. e.g. However, I also want to read the HTML response that is sent alongwith so that I can parse that. An example header exchange captured using LiveHTTPHeaders: Clearly, content-length is n...
