if (Request.Headers[“XYZComponent”].Count() > 0) … will attempted to count the number of characters in the returned string, but if the header doesn’t exist it will return NULL, hence why it’s throwing an exception. Your second example effectively does the same thing, it will search through the collection of Headers and return NULL if it doesn’t … Read more
Make a new default.aspx, and put this in the code behind: I cant test any further based on your current question, because you didn’t include a valid username/password. using System; using System.Web; using System.Net; using System.IO; using System.Web.UI; using System.Web.UI.WebControls; namespace Foo { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs … Read more
For which API-level do you need that function? Since API Level 8 there is a second loadUrl function: public void loadUrl (String url, Map<String, String> extraHeaders) With the extraHeaders you should be able to send a referrer. EDIT: Here is a complete working example: String url = “http://www.targetserver.tld/”; Map<String, String> extraHeaders = new HashMap<String, String>(); … Read more
I noticed that an HttpWebRequest hangs on the first request. I did some research and what seems to be happening is that the request is configuring or auto-detecting proxies. If you set request.Proxy = null; on the web request object, you might be able to avoid an initial delay. With proxy auto-detect: using (var response … Read more
Slap some tracing on it! Traces are your best friend when debugging these things. I once had one client which couldn’t connect to our SSL-enabled service. Using tracing I found that someone had moved the system clock past our certificate expiry date. But I digress. Enable all applicable trace sources and see if something interesting … Read more
Close enough: How can I send an HTTP POST request to a server from Excel using VBA? — It’s even for Excel 😉 Just use a GET request instead: objHTTP.Open “GET”, URL, False MSDN: Using the WinHttpRequest COM Object – Retrieving Data Using Visual Basic
There are two types of behaviour. One is rewrite, the other is redirect. Rewrite The server performs the substitution for itself, making a URL like http://example.org/my/beatuful/page be understood as http://example.org/index.php?page=my-beautiful-page With rewrite, the client does not see anything and redirection is internal only. No URL changes in the browser, just the server understands it differently. … Read more
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
It turns out that Digest authentication is fairly easy to implement. With our own implementation, we were able to use the full URI (including parameters) to generate the MD5 hash. That fixed the problem. In case someone hits this problem in the future, you can call the workaround like: var resultText = DigestAuthFixer.GrabResponse(“/dir/index.html”); The code … Read more
