Are you sure about the httpd_accel_host virtual think?? Not commonly
used, and requires redirector rules to rewrite the host IP addresses to
suitable webservers..

The redirector rule you posted could not match in the data you posted
with the above configuration.

Kind of.. "httpd_accel_host www.unav.es" in the 2.5 config above would
make them more equivalent..

That's fine.

Looks ok. You might want to use a ^/alumno/ga/ above however just in
case that string appears elsewere in a requested URL...

And if you use the normal Squid format you'll also see which parent it
was sent to.

This indicates the web server responded with a redirect. If you enable
log_mime_hdrs you will see the full server response, in there look for
the Location header to see where the redirect sent by the server was
going..
