/*
 * General notes: (ToDo stuff)
 *
 * 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.
