In 4.0 version of the .Net framework the ServicePointManager.SecurityProtocol only offered two options to set: Ssl3: Secure Socket Layer (SSL) 3.0 security protocol. Tls: Transport Layer Security (TLS) 1.0 security protocol In the next release of the framework the SecurityProtocolType enumerator got extended with the newer Tls protocols, so if your application can use th … Read more
If you are referring to the System.Net.HttpClient in .NET 4.5, you can get the content returned by GetAsync using the HttpResponseMessage.Content property as an HttpContent-derived object. You can then read the contents to a string using the HttpContent.ReadAsStringAsync method or as a stream using the ReadAsStreamAsync method. The HttpClient class documentation includes this example: HttpClient … Read more
Use the getHeader(String Name) method of the javax.servlet.http.HttpServletRequest object to retrieve the value of Remote_Addr variable. Here is the sample code: String ipAddress = request.getHeader(“Remote_Addr”); If this code returns empty string, then use this way: String ipAddress = request.getHeader(“HTTP_X_FORWARDED_FOR”); if (ipAddress == null) { ipAddress = request.getRemoteAddr(); }
Unfortunately, it doesnt look like you can customize this per service point. I would suggest that you file a feature request at the MS Connect website for this area. As a dirty workaround, you could try executing the sites that require a different security protocol in a new appdomain. Static instances are per appdomain, so … Read more
First install “Microsoft ASP.NET Web API Client” nuget package: PM > Install-Package Microsoft.AspNet.WebApi.Client Then use the following function to post your data: public static async Task<TResult> PostFormUrlEncoded<TResult>(string url, IEnumerable<KeyValuePair<string, string>> postData) { using (var httpClient = new HttpClient()) { using (var content = new FormUrlEncodedContent(postData)) { content.Headers.Clear(); content.Headers.Add(“Content-Type”, “application/x-www-form-urlencoded”); HttpResponseMessage response = await httpClient.PostAsync(url, content); … Read more
You can continue using WebClient to POST (instead of GET, which is the HTTP verb you’re currently using with DownloadString), but I think you’ll find it easier to work with the (slightly) lower-level classes WebRequest and WebResponse. There are two parts to this – the first is to post the login form, the second is … Read more
Console.Write((int)response.StatusCode); HttpStatusCode (the type of response.StatusCode) is an enumeration where the values of the members match the HTTP status codes, e.g. public enum HttpStatusCode { … Moved = 301, OK = 200, Redirect = 302, … }
Something like this should work (untested): public static class Extensions { public static async Task<HttpWebResponse> GetResponseAsync(this HttpWebRequest request, CancellationToken ct) { using (ct.Register(() => request.Abort(), useSynchronizationContext: false)) { var response = await request.GetResponseAsync(); ct.ThrowIfCancellationRequested(); return (HttpWebResponse)response; } } } In theory, if cancellation is requested on ct and request.Abort is invoked, await request.GetResponseAsync() should throw … Read more
You should be ok if you just call Close on your response. You are only allowed so many “open” connections, so the reason it is failing is because it can’t open a new connection. Once you are done with the response, you need to close it… no need to reuse anything. From the MSDN article: … Read more
It depends on how the website is authenticating users. If they are using basic authentication or Windows authentication, then you can set the Credentials property of the HttpWebRequest class to the username/password/domain information and it should work. However, it sounds like you have to enter the username/password on the site, which means you are going … Read more
