Re: [enhydra] user-agent session id question

["Radivoj Milin" <lola@xxxxxxxxxxxxx>]

Hi,

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.
