Handling 404 errors

[Andrew Hole <andremailinglist@xxxxxxxxx>]

Hi guys!

Actually our web application has a retry mechanism based on http status code returned to client. Just an example:
- An http request is made to http://web/software_A_folder/file.swf
- if the file doesn't exist (http 404) on software_A_folder, the request is made in core folder: http://web/core/file.swf

This mechanism is used on entire application: when a file doesn't exist on software_x_folder, a retry is made on core folder.

In terms of Apache, this mechanism make always 2 requests (in case of file not found).

What I want to know is if there are any option on Apache to handle 404 status code without retry the request. When file not found, some logic will handle the 404 and return the file located on other folder.

I appreciate your help.

Best Regards,
A.
