Subject Re: Implementing a logout
Date Sun, 23 Aug 2009 17:33:09 GMT
Just clarifying : My query was more specific to Solr. I wanted to check if
there are any Solr resources that are session-specific that we need to
release.

*>> I can't understand: do you use several web applications in a same

I have only one application that is built on top of Solr. I mentioned
SolrCore in my mail only because that was the only object that I noticed
which had a close() method. I don't intend to do a close() on SolrCore when
a particular user logs out (closes his session)

I understand Solr application does not have a logout. Please correct me if I
am wrong but you seem to be stating that there is no explicit action
required from our side to release any Solr resources when a user terminates
his/her session of a Solr based application. If that is the case, then my
query is answered.

Thank you all.

Regards
Rahul
