Topic: PunBB inside Rails - an apache tweak and cookie injection
I've recently worked out how to get my existing Rails app to house a PunBB forum install as well as manage the cookie creation/deletion for PunBB. This allows my Rails app to have single-sign-on with the forum under the same domain. My Rails app handles the usernames/passwords for the community and just syncs to the PunBB users table when necessary.
There were two parts - the first was getting PHP to render correctly...
The second was manipulating the cookie (for single-sign-on)...
Generating a Rails and PunBB (and DokuWiki) shared cookie
I hope this is helpful to someone - I couldn't find it documented anywhere else.
