I'm writing a filter in which two lines of data are to be appended to the content going back. However, I'd like to test for a 404, and if found set the response to 200. Can this be done from the output filters? Or am I going to have to do something more complex with a handler?
The big problem is mod_proxy (or any other module, for that matter) - it's not as simple as checking the file on disk - the content could be coming from a proxy or from another content-handler. Any ideas? Issac
