Re: [enhydra] user-agent session id question


Every request on presentation object is checked for session id(in cookie or in url).
If there is no session id in request the new session will be generated.
There is no option to prevent new session to be generated if session id is not found.

Parameter (in web.xml file) 'SessionManager.SessionEncodeUrlState' can be set to 'Never' to avoid session id to be stucked in the url. But in that case if browser has cookies disabled, for that user on every new request new session will be generated(because no session id is found in request).

If that cant resolve your problem you can try to create a custom session manager to support that scenario, one of solutions may be : Method 'createSession (HttpPresentationComms comms)' (in SessionManger) is called for generation of new session(if session id is not found in request). You can try to detect user-agent by calling 'comms.request.getHeader("user-agent")', and return special
session not create a new one.

Subject: [enhydra] user-agent session id question


I'm having some trouble with session ids and various search engine bots
hitting the same links over and over again because of the session ids
getting stuck on the url.  I looked into creating a custom SessionManager
that would reuse a special session whenever bots hit the site, but as far as I can tell, there's no way to detect the User-Agent from the SessionManager.

Does anyone have any thoughts or any ideas how prevent new session ids from
being generated for specific user-agents?  Thanks!
