It wasn't clear until recently that the input filters run during the handler phase (which is after the hooks). Could we clarify the order of events here so third party developers can see the flow? I believe the answer is no, but is it possible to subvert an input filter from being executed? Is there anything I should be aware of when running as an input filter that's different from running in the hooks? >I don't think it is clear where filters fall in the order of request processing.

As I told you, the HTTP_IN >filter has a couple of examples of how to do this. How could I possible do my access checking as a part of the input filter and deny access within the access checker if the access checker runs first? There are cases where I might want to deny access based on what I find in the input filter (did I say access enough here?). >While it is true that there isn't much information available for writing >input filters, the best source currently available is the filters used in >Apache itself. > >Ryan What about things like setting headers or performing a redirect from within an input filter? Are there examples of this as well. What input filters are good to look at besides ap_http_filter?
