You don't share the session. Each thread context should have its own
session.
You should not need to do anything with the alternative session at all.

Subject: [IBO] IBO 4.2ed & ISAPI modules


> hi,
>
> i'm building a high perf isapi web application using D6 webbroker,
> IIS5.0, IB5.6 and IBO4.2ed. everything worked fine (and fast) just
> until i tried to do http-redirects from one isapi-dll to another,
> which results in crashing the inetinfo process. what i did is:
>
> * place a tib_session in the webmodule (first in creation order)
> * place connection and transaction in the webmodule
> * use remote connection (localhost/tcpip)
> * create queries dynamically in oncreate of the webmodule,
> using the session in the webmodule as owner
> * do something (and a redirect)
> * free the queries in ondestroy of the webmodule
>
> my logs tell me that the first dll finishes fine, the second one
> doesn't get over the oncreate of the webmodule. i think it could be
> that the second one starts while the first one hasn't yet freed all
> of it's components - some of the queries are exactly the same in both
> modules, all of them use the same ib user and the problem also occurs
> when isapi caching is turned off.

> i read about SetAlternateSession method of tib_session: would i have
