You can register a cleanup on r->connection->pool and it will run when
the connection is cleaned up, but it's not clear if that's what you
mean by a "session".

Eric,
Got in doubt.. Sorry to bog you down with so much questions.
I think the same will serve for cleanup at the end of response.
Am i right ?

A cleanup at the end of a request should be registered against r->pool.

Eric,
Thanks for the clarification.
Just one more question.
My requirement is when request or associated reponse is served. I need to
clean up my memory functions.
I think your suggestion "r->connection->pool' will solve my problem.
Please confirm.

They're not initialized and destroyed together, e.g. keepalive.
See ssl_io_filter_init in modules/ssl/ssl_engine_io.c, except you'd
need to grab the conn_rec from the request_rec.

Hi Eric,
Thanks for the fast response.
By "Session" I mean when the request comes into the picture, the "c"
<Connection> and "r"<request_rec> parameters are intialized.
Session ends when the request is served. the "c" and "r" parameters got
destroyed or cleanup.
Can you please send me the code snippet to register the cleanup function as
you suggested.
