Incompatibility between Domain Access' db_prefix use and the current implementation of drupal_http_request

In the current drupal 6 release (6.13) there is a bug in drupal_http_request in that it expects $db_prefix to be a string. Modules like Domain Access place an array in that global variable which results in a preg_match error.

Dries already changed this behaviour in the CVS ( http://cvs.drupal.org/viewvc.py/drupal/drupal/includes/common.inc?r1=1.9... ), but until then you have to place the check in common.inc yourself in case you get the preg_match error on a page which uses an drupal_http_request.

This not a bug in the Domain Access module, just wanted to place FYI somewhere visible to Domain Access users.
