/*
* General notes: (ToDo stuff)
*
* Should support RFC2617 Digest auth.
*
* Support the ident protocol... the standard log format supports it.
* Add in support to pass connections through to a different webserver...
* probobly in access.ars... with like a simplified mod_rewrite.
* This would allow people to run apache and Synchronet as the same site.
