[wp-hackers] weird permalink issue

[Steve Taylor]

OK, an update to this. It seems that my "dynamic pages" system is
being scuppered any time the URL contains a slug that appears anywhere
in a real page or post elsewhere on the site. WP just redirects to the
real page or post.

My stuff is happening on the init hook - this code is being processed
on these requests. I do stuff like changing the HTTP headers to 200
later, in template_redirect - this code doesn't get processed.

Presumably WP's rewriting / redirecting happens in between. What's the
easiest way, in the init hook, to say to WP: "don't bother with the
redirecting on this one"?

I know there's probably better ways of doing what I'm doing, but (1)
it's been working so far, and (2) if WP is stepping in and not finding
a real page for the request, shouldn't it be giving a 404? I guess
it's some interference between my code and WP. Anyway, any ideas about
halting WP's actions would be great. I'm hammering through the hooks
now...

cheers,

Steve
