[squid-users] squid 3 accel mode, sourcehash?

Currently using squid2.5 in accelerator mode. Would like to look at
squid3 and use the reverse proxy enhancements it offers. Seemingly the
rproxy patch has been implemented in squid3.

Specifcally the 'originserver' directive to cache_peer I want to use,
along with 'sourcehash' that was in the rproxy patch. 'sourcehash'
however appears to be missing in squid3. Is this to be included in the
future ? Is there another way to get squid3 to do 'sticky' session load
balancing to origin servers ?

Thanks,
