SEO issue with Drupal Forums
There is an SEO issue with Drupal's forums similar to the SEO problem with Drupal views where pages that don't exist still send a 200 OK header.
This is the correct URL of a Drupal forum:
drupal.org/forum/1
This non-existant URL also sends a 200 OK header when it should send a 404 Not Found header:
drupal.org/forum/1/asdf.html
An example of where this might cause problems is when you take a non-Drupal forum and convert it to a Drupal forum that has different URLs.
Does anyone know how to fix it so that Drupal sends 404 headers when trying to access a forum URL that doesn't exist?


Global redirect
Do you have globalredirect installed?

Drupal forum seo
That's interesting -- the problem happens on Drupal.org's forums (no Global Redirect), but not on another couple of Drupal forums I checked that do have Global Redirect.
