I tried posting this first to the support list, but it might be a little too deep geek for that list. This is the only multisite issue I have been stumped by. The problem has to do with the url in the action parameter for the edit forms being created incorrectly (Note: only tested in 4.6). This problem only shows up for multisite, and only when I use apache & $base_url to make a multisite site look like a single site. For example the main CITRIS site is really located at citrissrv2.berkeley.edu/citris. It sits behind an apache server that does a proxy pass from www.citris-uc.org to citrissrv2.berkeley.edu/citris. Then I set the site's $base_url to www.citris-uc.org , and 90% of the time this works fine. However, when Drupal generates a edit forms, it prepends "/citris" to the url in the form's action parameter. So where it should have action="/node/123/edit", instead it generates action="/citris/node/123/edit". This does not happen when the $base_url is citrissrv2.berkeley.edu/citris and proxy pass is not used. To deal with this issue, I set up a symbolic link so that $durpal_dir/citris just points back to $drupal_dir. This is an easy fix that works most of the time. However, modules such as webform and project have forms that use secondary pages as subforms, and as the pages pass the data back-and-forth, I end up with urls like action="/citris/citris/citris/citris/citris/node/123/edit" and so on, until the url finally gets too long for the browser to handle, the url gets clipped & the user is set to an error page. I suspect I am going to be diving into core to address this one, but I still hope it might just be a configuration error on my part. I am grateful for any tip & leads.
