Hi,
Working on disco and result set management, I am wondering why there
is no cache management tools in XMPP.
Why not implement Etags, If-none-match and If-modified-since XMPP
versions ?
for rosters see: http://xmpp.org/extensions/inbox/roster-versioning.html
Best regards,
Stanzas can get very large in some disco cases, and traffic could be
greatly reduced, at a low cost of implementation.

While writing the previous example, stpeter's famously large roster
also came to my mind.
Implementing such a system could greatly reduce the load when the
user connect on both the server and the client.
I did a quick googling on XMPP cache managment. Nothing related came
up. Was there any previous talks about it ?
