Check at the IIS level, not ASP.NET level.
Check the IIS management console. Possible options are:
- «URL rewrite module»
- «HTTP redirect» (under the website settings, for IIS7)

I checked the web config and the only URL Rewrite I found is this — Request.ServerVariables[«logon_user»].ToString(). I’m not finding HTTP Redirect in IIS. Where specifically is it?

It can happen if you return a CSS file in ASP.NET over http when it should be over https, ive seen that happen in the past. Also if any web services tied into that application that are getting hit or making passes that fail, that could cause it too. Just shooting from my hip and trying to recall the last time I seen those issue’s arise.

Do you know how a failed service call will generate a 302? Doesn’t make sense to me. The app is making plenty of these, however.

You guys are correct, sorry. I thank you for your help.
I succeeded in setting up the logging.
Now the new file showed up in here: C:\inetpub\logs\FailedReqLogFiles\W3SVC1\fr000059.xml
There are many lines of log. I could find the problematic section in the log:
248. ASP_SCRIPT_TRACE_START FilePath="C:\INETPUB\WWWROOT\CT\DEFAULT.ASP"
249. ASP_SCRIPT_TRACE_COM_CALL_START FilePath="C:\INETPUB\WWWROOT\CT\CERTSBRT.INC", LineNumber="88", CurrentStatement="If sDirectory <> Left(Request.ServerVariables("URL"), 8) Then", SizeOfStatement="61"
250. ASP_SCRIPT_TRACE_COM_CALL_END FilePath="C:\INETPUB\WWWROOT\CT\CERTSBRT.INC", LineNumber="88", CurrentStatement="If sDirectory <> Left(Request.ServerVariables("URL"), 8) Then", SizeOfStatement="61"
251. ASP_SCRIPT_TRACE_COM_CALL_START FilePath="C:\INETPUB\WWWROOT\CT\CERTSBRT.INC", LineNumber="88", CurrentStatement="If sDirectory <> Left(Request.ServerVariables("URL"), 8) Then", SizeOfStatement="61"
252. ASP_SCRIPT_TRACE_COM_CALL_END FilePath="C:\INETPUB\WWWROOT\CT\CERTSBRT.INC", LineNumber="88", CurrentStatement="If sDirectory <> Left(Request.ServerVariables("URL"), 8) Then", SizeOfStatement="61"

258. ASP_SCRIPT_TRACE_COM_CALL_END FilePath="C:\INETPUB\WWWROOT\CT\CERTSBRT.INC", LineNumber="92", CurrentStatement="Response.Redirect sDirectory & Mid(Request.ServerVariables("URL"), 9)", SizeOfStatement="69"
259. ASP_SCRIPT_TRACE_COM_CALL_START FilePath="C:\INETPUB\WWWROOT\CT\CERTSBRT.INC", LineNumber="92", CurrentStatement="Response.Redirect sDirectory & Mid(Request.ServerVariables("URL"), 9)", SizeOfStatement="69"

261. ASP_SCRIPT_TRACE_COM_CALL_START FilePath="C:\INETPUB\WWWROOT\CT\CERTSBRT.INC", LineNumber="92", CurrentStatement="Response.Redirect sDirectory & Mid(Request.ServerVariables("URL"), 9)", SizeOfStatement="69"
262. ASP_SCRIPT_TRACE_COM_CALL_END FilePath="C:\INETPUB\WWWROOT\CT\CERTSBRT.INC", LineNumber="92", CurrentStatement="Response.Redirect sDirectory & Mid(Request.ServerVariables("URL"), 9)", SizeOfStatement="69"
263. ASP_SCRIPT_TRACE_END FilePath="C:\INETPUB\WWWROOT\CT\DEFAULT.ASP"
264. ASP_END_SCRIPT_EXECUTION
265. MODULE_SET_RESPONSE_SUCCESS_STATUS ModuleName="IsapiModule", Notification="EXECUTE_REQUEST_HANDLER", HttpStatus="302", HttpReason="Object moved"
266. NOTIFY_MODULE_COMPLETION ModuleName="IsapiModule", Notification="EXECUTE_REQUEST_HANDLER", fIsPostNotificationEvent="false", CompletionBytes="0", ErrorCode="The operation completed successfully.
(0x0)"
Now let’s look at the CERTSBRT.INC
It is originally a part of CertSvr folder, which I copied to «Ct» folder
87. ' first, make sure we have the right URL to prevent cookie problems.
88. If sDirectory <> Left(Request.ServerVariables("URL"), 8) Then
89. If 0<>Len(Request.ServerVariables("QUERY_STRING")) Then
90. Response.Redirect sDirectory & Mid(Request.ServerVariables("URL"), 9) & "?" & Request.ServerVariables("QUERY_STRING")
91. Else
92. Response.Redirect sDirectory & Mid(Request.ServerVariables("URL"), 9)
End If
Response.End
End If
The original error is line 88. I looked up the value of sDirectory, there is first mention in that file on line 6:
6. sDirectory = "/ct"
Back to the line 88, the statement Left(Request.ServerVariables(«URL»), 
is designed for string «/certsvr», therefore the length is 8.
Finally, the fix is to change the value in that statement on line 88. In my case «/ct» is 3 chars. The fixed line would be:
88. If sDirectory <> Left(Request.ServerVariables("URL"), 3) Then
So, I brought this all on myself just by copying the CertSrv folder and not paying the attention to details.
