Today I just wanted it to know. I've downloaded

• Apache 2.0.58 Windows binary
  (http://apache.autinity.de/httpd/binaries/win32/apache_2.0.58-win32-x86-no_ssl.msi)
• Apache mod_aspdotnet
  (http://www.apache.org/dist/httpd/mod_aspdotnet/mod_aspdotnet-2.0.0.msi)

and installed them, Apache as a console application running on port 8080. 

Afterwards I have copied  a fresh DotNetNuke 3.2.2 to c:\dnn, created a new database and configured my web.config like usual.

Now I have to setup apache to use asp.net and to create a virtual directory dnn. So I added the following lines:

LoadModule aspdotnet_module modules/mod_aspdotnet.so

# Use the asp.net handler for all common ASP.NET file types
AddHandler asp.net asax ascx ashx asmx aspx axd config cs csproj \
                   licx rem resources resx soap vb vbproj vsdisco webinfo

<IfModule mod_aspdotnet.cpp>

    # Mount the DotNetNuke  application
    AspNetMount /dnn "C:/dnn"

    # Map all requests for /StoreCSVS to the DotNetNuke application files
    Alias /dnn "C:/dnn"

    # Allow asp.net scripts to be executed inside DotNetNuke
    <Directory "C:/dnn">
        Options FollowSymlinks ExecCGI
        Order allow,deny
        Allow from all
        DirectoryIndex Default.htm Default.aspx
    </Directory>

    # 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"
    <Directory \
          "C:/Windows/Microsoft.NET/Framework/v*/ASP.NETClientFiles">
        Options FollowSymlinks
        Order allow,deny
        Allow from all
    </Directory>

</IfModule>

[Original version: http://httpd.apache.org/mod_aspdotnet/introduction#example]

I started apache, opened IE, navigate to http://localhost:8080/dnn and DotNetNuke started its installation - just for a few seconds to raise an error. Hiting [F5], new start of the installation, everything went through. Opened portal site, error again, [F5] and...

It worked, start page was showing up.

Further navigation was not possible as FriendlyUrls did not work. So I changed the settings by hand inside the hostsettings table and restarted apache.

Now it am able to login as host and open the admin pages. I am currently fighting with some java script errors, for example I can't add new pages. It is still far from production though this was more than I expected. I never worked with apache before and I was lucky to see what is possible in just about an hour.

Last notice:

It is quick. I have never seen such a fast startup of a dotnetnuke application using IIS. If I start a new apache process and  navigate to DNN it just takes about 8s before it is finally rendered.
