Close ITS-Session

Hi!

I' ve integrated some ITS-Services into a Web Dynpro ABAP Application (via IFrame View-Element), which I call with their absolute URL.

The problem I' m facing is that after opening 3 or 4 applications in sequence, I' m dumping because the server' s not able to allocate further memory - this because of every call opening a new session.

Is there a way to close the ITS-session via URL or ABAP?

Regards,

Thomas
