session - Why does my asp.net application recycle when I delete a folder? -

I have a Silverlight application using the hosted WCF service in IIS. I use some aspects of ASP.NET.

I have the following folder structure for my application:

  Inputup wwwroot myapp reports {user-guid-folders} report1 .pdf report 2.pdf App_Data (folder) Bin (folder) Client_Bin (folder) (various .aspx files, plus web.config, etc)  

The application dynamically generates reports and puts them in a unique name for the user For a folder with a GUID it all works fine.

However, when the user logs out, I was cleaning PDF files in my folder and then was removing their GUID folder.
