OpenDocument.jsp opens a session, is there a way to close it?

Hello,

I have a C# page that gets a token (using RESTful for BI 4.1) and necessary parameters to open a opendocument.jsp page.

So I open the opendocument.jsp page, everything works fine (I can see the report with the right data, it takes my parameters ok, etc)

But there is no option or button to close the session or disconnect in that page. The only possibility is to close the window using the top right hand side close (X) button.

When I go to the CMC I realise that even if I've closed the window, the session stays active (till timeout of the session, 1 hour later)

We have a limit of 50 concurrent licenses so it is in our interest to close the session as soon as possible:

is there a way to do that?

Thanks and kind regards,

Enrique
