I am experimenting with Apache on Windows XP. I have it installed at
its default location but I have the DocumentRoot changed to F:/www/. I
have mod_rewrite and mod_vhost_alias enabled. I am trying to have
Virtual Subdomains for each directory in my DocumentRoot. I have the
following VirtualHost set up and it works fine. I am wondering how to
do rewriting inside of the VirtualHost.
 <VirtualHost *:80>
  UseCanonicalName off
  VirtualDocumentRoot "F:/www/%0"
  VirtualScriptAlias "F:/www/%0/cgi-bin"
</VirtualHost> 
The specific rewrite I am trying to do is 
wayne.waynesimonsen.com/login/ =>
F:/www/wayne.waynesimonsen.com/index.php?action=login
It needs to change for each user so a different index.php is run
depending on the user.
When I look at the logs for the rewriting, it is prefixing the
documentroot. It needs to prefix the VirtualDocumentRoot.
