Modaspdotnet and virtual hosts... new to this!

[whitestream6]

I've (partially) managed to get modaspdotnet to run on apache.
This is my code:

LoadModule aspdotnet_module "modules/mod_aspdotnet.so"

AddHandler asp.net asax ascx ashx asmx aspx axd config cs csproj \
                 licx rem resources resx soap vb vbproj vsdisco webinfo
  # For all virtual ASP.NET webs, we need the aspnet_client files
  # to serve the client-side helper scripts.
  AliasMatch /aspnet_client/system_web/(\d+)_(\d+)_(\d+)_(\d+)/(.*) "C:/Windows/Microsoft.NET/Framework/v$1.$2.$3/ASP.NETClientFiles/$4"
<IfModule mod_aspdotnet.cpp> 
  # Mount the ASP.NET /asp application
  AspNetMount /SampleASP "c:/www/vhosts/localhost/SampleASP"
  #/SampleASP is the alias name for asp.net to execute
  #"c:/SampleASP" is the actual execution of files/folders  in that location

  # Map all requests for /asp to the application files
  Alias /SampleASP "c:/www/vhosts/localhost/SampleASP"
  #maps /SampleASP request to "c:/SampleASP"
  #now to get to the /SampleASP type http://localhost/SampleASP
  #It'll redirect http://localhost/SampleASP to "c:/SampleASP"

  # Allow asp.net scripts to be executed in the /SampleASP example
  <Directory "c:/www/vhosts/localhost/SampleASP">
    Options FollowSymlinks ExecCGI
    Order allow,deny
    Allow from all
    DirectoryIndex index.htm index.aspx
   #default the index page to .htm and .aspx
  </Directory> 
  <Directory "C:/Windows/Microsoft.NET/Framework/v$1.$2.$3/ASP.NETClientFiles/$4">
    Options FollowSymlinks
    Order allow,deny
    Allow from all
  </Directory>
</IfModule>

The example one mentioned above - sampleASP - works well, but it is hard for me to get it working for any other examples.

How do I get modaspdotnet to work properly with virtual hosts
(e.g. mysite1.com)?

I've tried, I've looked up on Google, but still struggling... any advice is appreciated!
