hi

I have a custom filter than when it finds a url in a forum post modifies it adding some html.

Everything works great, except, periodically it seems like the filter was skipped or that it could not match the text and thus didn't apply the html.

The thing that's driving me crazy is this happens on the same message that previously it was working on. If I do empty cache (via developer module) or edit and resave the message it's fine again for X amount of time.

I'm wondering does drupal sometimes feed the filter the incoming text in different ways?Could it sometimes be passing me text with half a url, and other times passing me text with the full url?

It's been driving me crazy for days can't figure it out ;(. I tried disabling all drupal caching as a possible workaround but that had no effect.

thanks for any help.
