Mozdev.org is currently evaluating using Drupal for serving portions of its and its supported projects' websites. Specifically, we're looking to add blogging, wikis, and forums immediately, then also work to migrate other content into the system.
Mozdev currently services its projects as subdomains (www.mozdev.org, project1.mozdev.org, project2.mozdev.org, etc). Since we're looking to only add certain functionality to each site right now we'd like to just enable Drupal at certain urls for each site, for example:
www.mozdev.org/blog
www.mozdev.org/forum
www.mozdev.org/wiki
www.mozdev.org/admin
project1.mozdev.org/blog
...
I have multi-site setup and working with clean urls for multiple sites by adding the other projects to the sites/ directory (this may be done from only inside the default site by setting the prefixes through scripting later), but I'm having problems pulling Drupal into an existing site using aliases while leaving the clean urls enabled.
My Apache virtualhost:
ServerName locdrupal
ServerAlias locdrupal locdrupal1 locdrupal2
DocumentRoot "/home/silfreed/src/mozdev/drupal/fakeroot"
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
