Commented Issue: Nuget.Server not working on AppHarbor [2716]

I decided to try and get Nuget.Server running. Easy. Then I deployed it to AppHarbor and ran into problems.

Here's my AppHarbor support thread:
http://support.appharbor.com/discussions/problems/7690-nugetserver-app-results-in-502-bad-gateway

Here's my AppHarbor app:

After reading a post on Stack Overflow, I got thinking that doing some sort of WCF config would help:

But maybe there's a problem with the code in the Helpers.GetBaseUrl call
https://nuget.codeplex.com/SourceControl/changeset/view/59669b360f7d#src%2fServer%2fInfrastructure%2fHelpers.cs

Especially considering AppHarbor's advice to use this package:
http://nuget.org/packages/Premotion.AspNet.AppHarbor.Integration

Sorry for all the links, but it's a lot to summarize. I'm posting here in case someone has already figured out how to get Nuget.Server running on AppHarbor.

Thanks in advance.
