Can/Should something be designated as a filter AND a handler? For example the filter would pre-process the request such as POST data etc. The handler would work on what the filter setup? Or do I completely not understand the Apache module struct?
Depends on what you want to do. The core handler can always do the heavy lifting for you, and better yet, if you replace the core when serving sql data or some other source, your 'filter' can still be run against the data.
If your module -is- a data store (think an sql database, a compressed archive system, or something like that), then it most definitely should be a handler.
Well what I'm doing right now has to do with XML-RPC (Web services). I went through a couple tutorials, and have a handle on the handler method, no pun intended. Unfortunately, I don't know how to access the POST data that is sent. None of the data in the request_rec seems to hold that, or a method for me to pull it from a request_rec sub structure.
I realize that there are already XML-RPC implementations out there. I'm doing this as a learning exercise, a fun and frustrating exercise, but a learning exercise. I like the way that the module stuff is setup, I just can't figure the best way to get the POST data. The only tutorial on input filters is the one at onlamp.com which is only playing with the first header field, and doesn't give me enough information on how it registered itself or set itself up at the beginning. So I started disecting httpd-2.0.52/modules/experimental/mod_charset_lite.c to try to figure that out, as of a few minutes ago my version compiled, though does nothing as of yet... I'm hoping to see what data gets passed through the filter. Which still doesn't help me understand where the handler would get the information that the filter dealt with...
One more question. I see a lot of ap_log_rerror() function calls in this module and in a grep -r ap_log_rerror * of the source tree, but not in the Doxygen generated docs. Why is that? If it is depreciated what should I use to log message? Basically I want to debug via printf type statements... It helps me learn where/when each function is called and in what order, and what the structure status is when it is called etc...
Is there another place to discuss 3rd Party modules? the modules list given on the http://httpd.apache.org/lists.html doesn't exist anymore?
Did you try [EMAIL PROTECTED] We've rearranged some infrastructure, so I've asked Adam to research ASAP.
I did try. The first time (yesterday or perhaps the day before) the subscribe request bounced. Today I tried again after your email, and I get a request for confirmation, which I reply to, and that is bounced now.
