We are having a problem where a single POST that is slow to respond is automatically resubmitted, causing duplicate requests and even slower performance.  This problem only happens on rewritten URL's.  If we submit directly to the target URL with the exact same parameters it never happens.

We're running 3.0.0.31 with default Proxy Settings of 60,30,30.  Before I update to the latest release I was wondering if changing the proxy settings to higher value should be tried first?  What happens if one of the timeouts is exceeded?  Does it auto-retry?  The descriptions of the proxy settings in the doc aren't helpful.  Please explain what is are Connect, Send and Recieve timeouts are and how I might use them for this problem?

This is an intranet application fronting a text search which is sometimes slow to respond.  We're running on Windows 2003 32-bit. 

Here is our http.conf:
AllowOverride None
RewriteEngine on
RewriteLog "C:\Program Files\Helicon\ISAPI_Rewrite3\URL_Rewrite.log"
RewriteLogLevel 3
ErrorLog "C:\Program Files\Helicon\ISAPI_Rewrite3\error.log"
LogLevel debug

Thanks for your help.
