[consulting] Running Drupal behind Reverse Proxy Server

[Chris Johnson]

We run a similar configuration, Pound in front of 2 web servers, with
multiple hostnames (foo.example.com, bar.example.com, woof.example.com).

Using Drupal 6, the only configuration changes we have to support this are:

$conf = array(
   'reverse_proxy' => TRUE,
   'reverse_proxy_addresses' => array('10.4.1.18'),
 );

We do not use any Session clause in our Service specification in the Pound
configuration.  It seems to work fine without it.  (I did not set it up
myself.)  That is, there are only Backend clauses.

For what it's worth.
