We are busy on a project that requires the application to be run on a windows 2003 server running Apache 2.2 as the primary internet server. Since IIS can run PHP applications, I figured that Apache would run dotnet without any problems. As it turns out there is a module for running dotnet application. It is however not very well supported and you have to make sure you get the Apache 2.2 version, which can be found here http://sourceforge.net/project/platformdownload.php?group_id=175077.

Dr Google pointed me to a very good tutorial for setting this up here, but I needed to configure it slightly differently as I have a whole lot of different virtual hosts. So this is very basically how my http.conf is setup

First off, with all the other modules you need to:

LoadModule aspdotnet_module "modules/mod_aspdotnet.so"

You then need to add a pointer to the Asp.net Client files like this:

#AddHandler fro asp.net
 AddHandler asp.net asax ascx ashx asmx aspx axd config cs csproj licx rem resources resx soap vb vbproj vsdisco webinfo 
 
 AliasMatch /aspnet_client/system_web/(\d+)_(\d+)_(\d+)_(\d+)/(.*) "C:/Windows/Microsoft.NET/Framework/v$1.$2.$3/ASP.NETClientFiles/$4" 
  <Directory "C:/Windows/Microsoft.NET/Framework/v*/ASP.NETClientFiles"> 
    Options FollowSymlinks 
    Order allow,deny 
    Allow from all 
  </Directory>

And then finally, you configure your virtual host:

<VirtualHost 127.0.0.1>
    ServerName server.aspnetsite
    DocumentRoot "D:/httpd/aspnetsite"
   
   AspNetMount / "D:/httpd/aspnetsite" 
   #Alias / "D:/httpd/aspnetsite" 
   <Directory "D:/httpd/aspnetsite"> 
   Options FollowSymlinks ExecCGI 
   Order allow,deny 
   Allow from all 
   DirectoryIndex Default.htm Default.html Default.aspx default.aspx
</Directory> 

</VirtualHost>

As you can see, I have mounted using the root (/). This is because I want my site to run from the root of my virtual host. If I wanted it to run form a virtual directory, I would have had "/Virtual" and then I would need to uncomment the "Alias" and specift "/Virtual" for that as well.

Hope this helps out for those who need it!
