title: Integrating an existing ASP.NET application into SharePoint
body: <p>What do I need to do to integrate an existing ASP.NET application into SharePoint? Are there any pitfalls, difficulties or is it a relatively easy process?
  I'm completely new to SharePoint. 
  The version of the ASP.NET app is 3.5
  The version of SharePoint is 3.0 (2007) running on IIS 6.
  Thanks</p>
