问题 I have a jquery ajax POST to a code-behind webmethod. In that webmethod i do a HttpWebRequest to a third party web api service that returns json. Even though the httpwebrequest works fine, a popup appears in the browser asking me to enter credentials (authentication required). On my machine this works well, however when deployed it doesn't except if there is no data returned from the httpwebrequest call. The jquery call: function serverCall(httpMethod, pageName, methodName, inputData,

Getting remote file size without content-length

由 落花浮王杯 提交于 2019-12-25 03:45:18
问题 so I've figured on how to get remote files their file size from over the internet with the following code: WebRequest req = WebRequest.Create(url); req.Method = "HEAD"; using (WebResponse resp = req.GetResponse()) { int ContentLength; if (int.TryParse(resp.Headers.Get("Content-Length"), out ContentLength)) { // Stuff ~ } } How do I get a remote file its size without the Content-Length option? I'm really out of ideas and I've searched the internet for several hours, being unable to find it. If

On WP8.1 ONLY: cannot read more than 65536 bytes off an HTTP Stream

问题 Hope someone could please provide any help on an issue I'm struggling for quite a lot of time. Goal : I need to read an http stream from a specified URI, that I startup & endlessly read with the following code (which I stripped down to minimum so to really focus on the bare communication problem): public void StartupStream(Uri uri) { HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(uri); // Start the asynchronous request request.BeginGetResponse(OnGetResponse, request); }

HttpWebRequest timeout in 3.5sp1

由 ﹥＞﹥吖頭↗ 提交于 2019-12-25 02:27:11
问题 We have a service that opens several HttpWebRequests. It ran fine under 3.0 until we upgraded the server to .net 3.5sp1. Now we get timeouts while waiting for the request. (we have verified that the endpoint is up and running). There are a few things that make this interesting. Increasing the number of max connections will let it run for a little longer before the timeouts occur. Also, once we see the requests waiting, if we open Fiddler they all succeed. These requests open via a Timer

We want to get the post data from this postback url but within the webview or within our app. Tried intercepting the url load with this code: final WebView webview = new WebView(this

Silverlight 4 HttpWebRequest user agent string is null

问题 The problem I have a page with a silverlight object. It attempts to retrieve XML from another (external cross domain) page. But I am struggling with a security exception. I have this code working brilliantly in WPF. When using a website hosting a silverlight application with the same code, the user agent string of the HttpRequest object is null (and seemingly cannot be set). In fact there is no header information at all - this causes a security exception when attempting to make my
