Here’s some links that will help: Fiddler Web Debugging – Configuring Clients Which in turn links to here: Take the Burden Off Users with Automatic Configuration in .NET You can achieve this via … Read more
If the question is only “How to transfer Webbrowser authentication information to Webrequest or Webclient?” this code is enough: You can call the GetUriCookieContainer method that returns you a CookieContainer that can be used for subsequent call with WebRequest object. [DllImport(“wininet.dll”, SetLastError = true)] public static extern bool InternetGetCookieEx( string url, string cookieName, StringBuilder cookieData, … Read more
The following should get you started byte[] buffer = …request data as bytes var webReq = (HttpWebRequest) WebRequest.Create(“http://127.0.0.1/target”); webReq.Method = “REQUIRED METHOD”; webReq.ContentType = “REQUIRED CONTENT TYPE”; webReq.ContentLength = buffer.Length; var reqStream = webReq.GetRequestStream(); reqStream.Write(buffer, 0, buffer.Length); reqStream.Close(); var webResp = (HttpWebResponse) webReq.GetResponse();
Ya this can be quite annoying when web pages use status codes heavily and not all of them are errors. Which can make processing the body quite a pain. Personally I use this extension method for getting the response. public static class HttpWebResponseExt { public static HttpWebResponse GetResponseNoException(this HttpWebRequest req) { try { return (HttpWebResponse)req.GetResponse(); … Read more
I found the solution at this fiddler2.com page Why don’t I see traffic sent to http://localhost or http://127.0.0.1? Internet Explorer and the .NET Framework are hardcoded not to send requests for Localhost through any proxies, and as a proxy, Fiddler will not receive such traffic. The simplest workaround is to use your machine name as … Read more
I had a similar question, and the answers here did not give me the information I needed. So even though there is an accepted answer, I’m going to add what I’ve learned to help the next guy. 1) As some of the other answers mention, you can use using for the streams returned from HttpWebRequest/WebRequest. … Read more
I solved the problem with this: ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback ( delegate { return true; } );
Use stream to write content to webrequest string data = “username=<value>&password=<value>”; //replace <value> byte[] dataStream = Encoding.UTF8.GetBytes(data); private string urlPath = “http://xxx.xxx.xxx/manager/”; string request = urlPath + “index.php/org/get_org_form”; WebRequest webRequest = WebRequest.Create(request); webRequest.Method = “POST”; webRequest.ContentType = “application/x-www-form-urlencoded”; webRequest.ContentLength = dataStream.Length; Stream newStream=webRequest.GetRequestStream(); // Send the data. newStream.Write(dataStream,0,dataStream.Length); newStream.Close(); WebResponse webResponse = webRequest.GetResponse();
If you use either of them with async it should be good for the performance point of view as it will not block the resources waiting for the response and you will get good throughput. HttpClient is preferred over HttpWebRequest due to async methods available out of the box and you would not have to … Read more
On the heels of the previous answers, I wanted to add a couple more things. By default HttpWebRequest allows only 2 connections to the same host (this is HTTP 1.1 “niceness”), Yes, it can be overriden, no I won’t tell you how in this question, you have to ask another one 🙂 I think you … Read more
