Session wide variables across script requests

Hi,

I have a SOAP client which executes runScript method.

Three SOAP requests, one after the other, call runScript and execute a corresponding jsx on server.

Can I have some session/global-wide variables that I can access across scripts?

For example, during execution of first script, I set some variable. And again during the second and third SOAP requests, I use the variable (set in 1st script) in the 2nd and 3rd scripts.

I see that BeginSession allows you to work on a particular session. But can I set some session-wide variables?

How can I achieve the above?

I would really appreciate some help on this.
