"There are a couple of especially tricky bits: By default,
mod_rewrite
runs before the other URI translation modules (mod_alias
etc.) so if they are used then mod_rewrite must be configured
to accommodate them. Also, mome magic must
be performed to do a per-dynamic-virtual-host equivalent of ScriptAlias"http://httpd.apache.org/docs-2.0/vhosts/mass.html
