Hi,
So "location_rewrite_*" will not be useful until 3.2? I hope it will not
be too long to make my boss fire me :-)
I did not say that. :) you can always patch Squid yourself or have
someone do it for you.
3.2 is available _now_ if you don't mind running alpha quality code that
_will_ change. Any work done towards porting this feature will go in
there and be usable soon after acceptance.
Could I example my problem more ? maybe you or someone can help me for this:
1) user === www.a.com <http://www.a.com> ===> squid server
2) squid server know www.a.com <http://www.a.com> is another name of
www.b.com <http://www.b.com>, so it request www.b.com
<http://www.b.com> for caching
3) squid server === www.b.com <http://www.b.com> ===> www.b.com
<http://www.b.com> server
4) www.b.com <http://www.b.com> server receive request of www.b.com
<http://www.b.com> and then he want user to rediect to
www.b.com/beta/index.html <http://www.b.com/beta/index.html>
5) www.b.com <http://www.b.com> === redirect message ===> squid server
6) squid server === redirect message ===> user
7) user redirect to www.b.com/beta/index.html
<http://www.b.com/beta/index.html> (PROBLEM!!!, it should be changed to
www.a.com/beta/index.html <http://www.a.com/beta/index.html>)
what we want is the redirect message can be changed to
www.a.com/beta/index.html <http://www.a.com/beta/index.html>, so user
can still use our squid caching. How can I do ?
Hmm, I've been considering a relatively minor change to deny_info that
will clean this up, but its not ready yet either :(
There are a few ways to do it in all squid:
- The one most people seem to like is a url_rewrite_program helper
- The 'proper' HTTP-based way to do it is this:
acl httpSafeRedirectA dstdomain www.a.com
deny_info http://www.b.com httpSafeRedirectA
http_acecss deny httpSafeRedirectA
... the problem there is that sub-page requests get redirected to the
root of the alternate domain.
So you will need a 'catcher' script to do a second redirect
deny_info http://www.b.com/foo.cgi?%s httpSafeRedirectA
script does:
www.a.com/foo.cgi?http://www.b.com/beta/index.html ->
(301 permanent move) -> www.a.com/beta/index.html
I'm working right now on a patch that will resolve the extra config
hassle and scripting.
