He got hit with another one today. The access log fills to the maximum file size, then squid dies. Having squid return a reasonable error to the client may be a problem. It would probably be sufficient if squid did not cache the 301/302 return if the Location: field points to the requested URL. We'd still have the loop, but the remote access to the web server will rate-limit the loop and make it more apparent to the web administrators.

If the two are the same it's a loop. If it's cacheble yes. Regards Henrik
