dynamiccally creating/deleting directories

[dannystommen]

I'm dynamically creating and deleting some directories. They are created in the folder ~/data/backup.

Creating and deleting works fine, however, as soon as I delete a directory, IIS recycles the sessionpool, all sessions are gone and the user needs to log in again.

The applicationend log

_shutDownMessage=Directory rename change notification for 'D:\Websites\mysite.com'.
mysite.com dir change or directory rename
HostingEnvironment initiated shutdown
HostingEnvironment caused shutdown

_shutDownStack= at System.Environment.get_StackTrace()

is there anyway to prevend this for happening?
