WordPress MU

Hello all. I'm working on a plugin that due to its nature must do meta lookups on a post_id before wp_query and wp_redirect are instantiated by WPMU. I'm using pretty URLs on my blog, such as:

http://blogs.example.com/blog_name/path/to/page/

Can anyone offer me advice on the best way to get the post_id of the requested URL? Is it possible without messing up the rest of the request?

Thanks,
Mark

Bump -- can anybody point me in the right direction?

Would maybe get_page_by_path() help you?

That did the job nicely; thank you.
