Mono - ASP.NET Application in domain Subfolder

I have an Apache server with mod_mono hooked up to a legacy ASP.NET application. I can't seem to get this application to work if I move it from a top level folder.

For example, the following mono .webapp successfully works at http://localhost/Service.asmx (as my web app is in folder2):

<apps>
<web-application>
                <name>Test</name>
                <vpath>/</vpath>
                <path>/srv/aspnettest/folder1/folder2</path>
                <vhost>localhost</vhost>
        </web-application>
</apps>

However, due to a legacy URL, I need my web application to exist two subfolders deeper like so:

<apps>
<web-application>
                <name>Test</name>
                <vpath>/</vpath>
                <path>/srv/aspnettest/</path>
                <vhost>localhost</vhost>
        </web-application>
</apps>

If I try to go to http://localhost/folder1/folder2/Service.asmx it fails with

HTTP 500. Error processing request.

How can I successfully get a web app in subfolders? Thanks.

Turns out this was an Apache configuration issue that was unrelated but caused this as a side effect. I had my VirtualHost setup incorrectly.
