Here's what I have thus far: Stream requestStream; HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://wwwcie.ups.com/ups.app/xml/Track"); request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = postData.Length; requestStream = request.GetRequestStream(); XmlSerializerNamespaces xsm = new XmlSerializerNamespaces(); xsm

问题 We've introduced a few .NET pages into a Classic ASP application. When a user hits one of the .NET pages we use an HttpWebRequest to get session variable values from the ASP side by sending the request to a Class ASP page with the name of the session variable we want. This approach works, except in the following situation. On our production servers our IT folks have disabled the weak cipher algorithms with some registry hacking.

问题 When a web server responds to HttpWebRequest.GetResponse() with HTTP 304 (Not Modified), GetResponse() thows a WebException , which is so very weird to me. Is this by design or am I missing something obvious here? 回答1: Ok, this seems to be a by-design behavior and a perfect example of a vexing exception. This can be solved with this: public static HttpWebResponse GetHttpResponse(this HttpWebRequest request) { try { return (HttpWebResponse) request.GetResponse(); } catch (WebException ex) { if

问题 In my app, the user need to be authenticated on the server to download data using WebAPIs. The MvvmCross DownloadCache plugin seems to handle only basic HTTP GET queries. I can't add my authentication token in the url as it's a big SAML token. How can I add a HTTP header to queries done through DownloadCache plugin ? With the current version I think I should inject my own IMvxHttpFileDownloader but I'm looking for an easier solution. Injecting my own MvxFileDownloadRequest would be better
