[squid-users] storeurl_rewrite issues

Hey there!

I'm having some troubles with the storeurl_rewrite functionality in Squid.

Basic problem:
I am successfully able to run the external rewrite program, and a valid value is returned to Squid (as evidenced in cache.log), but then Squid just hangs, and never does any cache lookups or fetches to the URLs (access.log never gets written to).� Is there a step in which I have to pass the results somewhere in order for the processing to continue?

When I turn off the storeurl_rewrite program, everything works fine.� I receive TCP_HITs and TCP_MISSes (as expected) for the various URLs that I am trying to hit. �However, when I turn on the storeurl_rewrite (i.e., modify the config), I see the problems stated above.

A little more detail:
I am using Squid locally to cache external requests made by an application that I have. This app runs on Tomcat 5.5, which is set it up to route through Squid.� Essentially, the application makes calls to 3rd parties (with dynamic parameters in the URL), and I want to be able to slightly modify these calls so that the dynamic parameters do not cause new entries to be created in Squid.

One thing I noticed is that the HTTP Request File Descriptors are not closing (see last line of the log file).� I tried modifying the config to close these (half_closed_clients off), but that didn't seem to help.� I also tried modifying the storeurl_children parameter, but that didn't help either.

Any help is greatly appreciated.� Thanks!
Mark
