Squid and HTTP Headers

[spazeman]

I'm running squid now on my new server and since i've loaded vB last week, i'm having problems with headers. namely i need to get vBulletin code too use HTTP_X_FORWARDED_FOR instead of REMOTE_ADDR.

any ideas?

i am assuming i have to edit the 'get session' lines in infoadmin/sessions.php...

:confused:

If you're using Apache, try mod_proxy_add_forward.

I used it with fat mod_perl apache backend running mod_proxy and a thin apache front end running mod_proxy_add_forward.

Basically, it converts the headers for you

It should work with Squid, but I can't promise you.

You'll need to create a Perl script called proxy_conf.pl or something:

use Apache::Constants ();
sub My::ProxyRemoteAddr ($) {
my $r = shift;

# we'll only look at the X-Forwarded-For header if the requests
# comes from our proxy at localhost
return Apache::Constants::OK
unless ($r->connection->remote_ip eq "127.0.0.1")
and $r->header_in('X-Forwarded-For');

# Select last value in the chain -- original client's ip
if (my ($ip) = $r->headers_in->{'X-Forwarded-For'} =~ /([^,\s]+)$/) {
$r->connection->remote_ip($ip);
}

return Apache::Constants::OK;
}
1;

and then load it from httpd.conf

PerlRequire /etc/httpd/conf/proxy_conf.pl
