Re: How does WO enforce serial request processing per session?

We have a situation where we Single Sign On with a 3rd party system. When the user SSO's into our system, we need to keep their session alive in that 3rd party system for when the user re-enters that system. We do this by having a set of TimerTask's firing every X minutes. The idea is that if we detect that the user's session in the 3rd party system is no longer valid, we have to kick the user off our session. Essentially, logging the user out of our system.

In this case, we need access to our WOSession in order to log the user out.

Thanks

What if I access and use a WOSession outside of the request-response loop? Do i have to ensure that i call WOApplication.saveSessionForContext() when i am done using it?

Yes, that is what checks it back in.

May I ask why you want to access the session outside of a RR loop?  Perhaps there is a better way to do what you need done.

Hi List,

I was wondering how WebObjects enforces serial access to the WOSession (ie. request processing).

Does the "wo" request handler enforce serial access? Does the"wa" request handler enforce serial access? Does Application.dispatchRequest() enforce serial access?

Also, if I was to access a WOSession outside of a request-response loop, how can I ensure that the WOSession is not processing a request at the same time? How can I ensure that only one Thread accesses the WOSession at a time that comes from a "da" request? How do I initialise the WOSession correctly if I need access to it when not coming from a "wo" request the "wosid" is not sent along with a "wa" request?

See WOSessionStore and related methods in WOApplication.  See Practical WebObjects pages 171 - 172,

Is WOApplication.restoreSessionWithID() going to do "the right thing" when ever I call it? ie. is it going to initialize the WOSession correctly? will it ensure serial access to the WOSession? etc...

Yes.

Chuck
