RE: [squid-users] Squid reverse proxy - URL change in the response

Hi Cris,

Yes, I tried

        redirect_rewrites_host_header off

with the same result.

It looks to me Squid is not rewriting the URL of the response to look like
that of the request. The Web/J2EE application is using lots of redirects
and whatever it receives from Squid server ( httpd_accel_host &
httpd_accel_port) it sends back in the response in the Location HTTP
header.

So, probably I would need actually Squid to rewrite the host headers. I
was hoping I could achieve this effect through Squid configuration
directives but it looks to me now this is not possible. I'll check if
redirectors in Squid could help me control the response.

Thanks,

Dimitar

Did you try the "redirect_rewrites_host_header off"? It sounds like that
might be the cause, as it defaults to "on".
