crazy string in url problem

Question

I am working on asp.net 2.0.

Currently I started project that has been 80% developed by other.

when it comes to my hand there was no problem.

But suddenly I saw a problem in URL, e.g.

http://localhost:1281/MyProject/(S(tvrt5hnlt5tlwemdyjwrobjw))/Admin/WelcomeAdmin.aspx

so there is a crazy string between project Folder & subfolder or any subfile.

And it is amazing that it's not affecting My project.

But I want to know form where it comes and how? any guess?
