Yes, no problem with that. Put the hash on the server config, of course. There are a couple of caveats. Of course you'll need to use a thread mutex when you update the hash during request processing. Put the mutex on the server config, and create it in child_init. It would also be good practice to have your module create its own subpool of the process pool (also in child_init), rather than use the process pool itself in request processing. Make sure your hash entries, as well as the hash itself, are tied to your module's pool: the request pool will of course go out of scope far too quickly! The hardest bit if you're deleting hash entries is doing that without giving rise to a memory leak. If it's sufficiently rare you might just live with it; otherwise you should endeavour to re-use memory, or implement garbage collection on your module pool. BTW, the apache-modules list would be more on-topic for this. -- Nick Kew --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
