    <p>I have a site that has a strange behavior :</p> <p>When hitting a page which need an authentication, we treat it like this :</p> <ul> <li>a http module detects the need for authentication =></li> </ul> <p>returns status 401 : </p> <pre><code>context.Response.StatusCode = 401; // Prevents any other content from being sent to the browser context.Response.SuppressContent = true; // Directs the thread to finish, bypassing additional processing context.ApplicationInstance.CompleteRequest(); </code></pre> <ul> <li>the redirection to the auth form is detected and a redirection is done to the appropriate login form :</li> </ul> <p>Redirect code :</p> <pre><code>context.Response.Redirect(url, false); // Directs the thread to finish, bypassing additional processing context.ApplicationInstance.CompleteRequest(); </code></pre> <p>When a site with this code runs on IIS7 no problem is observed. But with IIS 6 the login form takes 2 minutes and counting to load (with IE, Firefox, sometimes it works fine with Chrome but not always).</p> <p>When using fiddler I can see the header (302 : redirect to the final login form) is received pretty fast but the browser waits for "ServerDoneResponse" to redirect and it takes at least 2 minutes.</p> <p>At first, there was no CompleteRequest() and I thought adding it will solve the problem but it hasn't.</p> <p>Does anybody have any idea about the problem ?</p> <p>Thanks in advance</p> <p><strong>Edit</strong> : the problem occurs on a site hosted on Windows 2003 R2 SP2</p> <p><strong>Edit #2</strong> : Information given by Fiddler :</p> <pre><code>ClientConnected: 14:27:39.219 ClientBeginRequest: 14:27:39.297 GotRequestHeaders: 14:27:39.297 ClientDoneRequest: 14:27:39.297 Determine Gateway: 0ms DNS Lookup: 0ms TCP/IP Connect: 0ms HTTPS Handshake: 0ms ServerConnected: 14:27:39.250 FiddlerBeginRequest:14:27:39.297 ServerGotRequest: 14:27:39.297 ServerBeginResponse:14:27:39.328 GotResponseHeaders: 14:27:39.328 ServerDoneResponse: 14:29:48.867 ClientBeginResponse:14:29:48.867 ClientDoneResponse: 14:29:48.867 Overall Elapsed: 00:02:09.5694285 </code></pre>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
