Subject RE: Implementing a logout
Date Sun, 23 Aug 2009 19:02:14 GMT
Truly correct:

- SOLR does not create HttpSession for user access to Admin screens (do we
have any other screens of UI?)
- SolrCore is shared object; closing it and reopening for each user session
is extremely expensive; this object requires gigabytes of RAM in even
simplest scenario

User doesn't have any session with SOLR based application. User may have
session with different application, and this one may use resources provided
by SOLR.

"release any SOLR resources" - no need. 

Of course, user session may store pointers to thousands documents retrieved
via SOLR query, - just close the session object.
