[drupal-support] Multiple HTTP Servers, one database?

Hi,

sorry, if this may be a FAQ, but at least a search for "load balancing" or "cluster" on this list did not produce meaningful hits.

We have a system, which is currently running on a single Apache server with a database. For reasons of load balancing and high availability, we would like to have multiple httpd's on different machines.

Is this possible with Drupal? Is it supported somehow? What is the recommended setup? (Which Apache module, if any, login dispatcher, whatever) Does the application need to support the setup?

Regards,

Jochen
