Thanks Henrik, Changed the helper to concurrency 0 and the 302 is now working. Only issue now is that the Location value is empty. However, when I test my script from the dos prompt in squid/sbin I see the floowing response from my script onto the cmd line 302:http://www.fancygear.co.uk Any ideas? Thanks again Alan -----Original Message----- From: Henrik Nordstrom [mailto:henrik@xxxxxxxxxxxxxxxxxxx] Sent: 12 March 2007 15:08 To: WRIGHT Alan Cc: squid-users@xxxxxxxxxxxxxxx Subject: Re: Question on 302 problem mån 2007-03-12 klockan 14:59 +0100 skrev WRIGHT Alan: > 2007/03/09 12:38:34| helperHandleRead: unexpected reply on channel 302 > from url_rewriter #5 '302:www.rachalan.f2s.com' > > In the cache.log file. > > Any ideas what the problem is? Looks like you have set url_rewrite_concurrency with a helper not supporting this modified helper protocol. Regards Henrik
