If I set a http header to a 404, will the page then stop processing? It seems that way on one server but on another it continues to process what's on the page. I would prefer to have it continue to process so that I can provide further error messaging on the page. Is it a setting on the server perhaps?

Ok, Ive not given a good example. Its not just 404 pages, its any error page ie. 400's and 500's. If I set my header to any error code it seems to stop running the page. I want to set the header and then display an error message but it seems when it receives the header the page stops running and never displays the error message.LeeTee– LeeTee2012-05-21 09:51:38 +00:00Commented May 21, 2012 at 9:51

In fact please see my other post for more in depth example and showing the code. stackoverflow.com/questions/10653978/…LeeTee– LeeTee2012-05-21 11:47:26 +00:00Commented May 21, 2012 at 11:47

When you raise a 404 error, the page doesn't stop processing. Except if you ask it explicitly.
Simple non-technical example: If the page stopped processing, there wouldn't be sites with a custom 404 page. :)

The page will still process, otherwise custom 404 pages woundn't be possible. Make sure you have error reporting turned on, as you may have a PHP error that's causing the script to stop running before the page is generated.

Turns out it was an issue with CURL. Thanks for your help.
