    <p>I have a problem with sending a POST request from C# to a PHP script on my Apache (Windows) server. Everything works fine, unless I instruct Apache to require a valid user using BASIC authentication through a <code>.htaccess</code> file.</p> <p>But let's put things in order. I'm using the following code to send a list of key/value pairs to my PHP script using HTTP-POST:</p> <pre><code>NameValueCollection nameValues = new NameValueCollection(); nameValues["operation"] = ...; nameValues["order"] = ...; nameValues["status"] = ...; nameValues["comment"] = ...; nameValues["user"] = ...; WebClient webClient = new WebClient(); try { CredentialCache credentialCache = new CredentialCache(); credentialCache.Add(new Uri(PERFORM_URL), "Basic", new NetworkCredential(PERFORM_USER, PERFORM_PASSWORD)); webClient.Credentials = credentialCache; byte[] response = webClient.UploadValues(PERFORM_URL, "POST", nameValues); string responseString = Encoding.ASCII.GetString(response); } finally { webClient.Dispose(); } </code></pre> <p>The PHP script on the server looks like this:</p> <pre><code>&lt;?php print_r($_SERVER); ?&gt; </code></pre> <p>So I just output some header information here. I turn off basic authentication in my <code>htaccess</code> file, everything's fine. When I turn it on, however, I get the following output:</p> <pre><code>Array ( ... [REMOTE_USER] =&gt; **** [AUTH_TYPE] =&gt; Basic [GATEWAY_INTERFACE] =&gt; CGI/1.1 [SERVER_PROTOCOL] =&gt; HTTP/1.1 [REQUEST_METHOD] =&gt; operation=updatestatus&amp;order=185&amp;status=17&amp;comment=Test&amp;user=somenamePOST [QUERY_STRING] =&gt; ... [PHP_AUTH_USER] =&gt; **** [PHP_AUTH_PW] =&gt; **** [REQUEST_TIME] =&gt; 1286889387 [argv] =&gt; Array ( ) [argc] =&gt; 0 ) </code></pre> <p>Where, the <code>REQUEST_METHOD</code> contains all the parameters + the appended <code>POST</code>. This is wrong. What can I do about it? I've also read and tried solutions, where people used <code>HttpWebRequest</code> using the <code>PreAuthenticate</code> property - but that didn't work for me either.</p>

    1. COWhat's the actual response on the wire? Knowing that would help tell if the bug was in the C# part or the PHP part.

    2. COMy C# code receives the output I gave in the last code fragment. I didn't debug the actual HTTP communication - how would I do that? What is it that you want to see?

    3. COThe best thing to do would probably be to get Wireshark going on the network between them, and watching the raw TCP traffic to see if it's even valid HTTP that C# is sending... If not, you at least know it's in C# (either your code, or a bug in the library that you're using)...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
