Running ASP.NET app within a SharePoint Virtual Server
For my own development efforts, I use Axosoft's OnTime product which is free for a single user (yeah!). I have a single SSL for Axosoft and for my WSS Team Site installation, so I needed for both to coexist peacefully in a single virtual server. Out of the box Axosoft was throwing several errors, at which point I came across this link from Microsoft:
How to enable an ASP.Net application to run on a SharePoint virtual server
After completing the steps in the article OnTime began working flawlessly! Nice!
