why can't I access SessionState from custom HttpHandler?

[Ralf Müller]

hi all!

in my custom HttpHandler HttpContext.Current.Session is not set - why?

greetings, ralf

The SessionState is handled by an HttpHandler, and it's possible that your
HttpHandler is called before the SessionState HttpHandler.

By implents the IRequiresSessionState (marker interface), you prevent your
HttpHandler to be called before the SessionState HttpHanlder, and so you can
use the session.

Wow! Thank you very much! Didn't expect the solution to be that easy...

Hello Cyril S.,

And if you only require read only session state, you implement IReadOnlySessionState
instead of IRequireSessionState.
