+Changes to squid-1.1.alpha17:
+
+ - Added more IMS support. Now Squid issues IMS requests for
+ expired objects in the cache. Log type will be either
+ TCP_EXPIRED_HIT if the server sends "304 Not Modified" or
+ TCP_EXPIRED_MISS if the server send a new object.
+ - Fixed storeGetMemSpace() bug; need to check
+ storeCheckPurgeMem() instead of storeEntryLocked().
+ - Renamed icp_hit_or_miss() to icpProcessRequest().
+ - Changed mkrfc850() to use normal variable instaed of a
+ pointer.
+ - Removed store_entry member from fd_table[] in comm.h.
+ - Changed httpSendRequest to not tack Squid onto the 'User-Agent'
+ line, Use HTTP/1.1 'Forwarded' instead.
+ - Removed icpProcessHIT() which only called icpSendMoreData().
+ - Removed icpProcessIMS() which only called icpGetHeadersForIMS().
+ - Removed some 'Reset header fields for reply' crap.
+ - added old_entry member to icpStateData for handling IMS
+ requests.
+ - Added 'locks' member to ipcache_entry; need to lock an
+ ipcache entry during ipcache_call_pending().
+ - Removed ipcache_call_pending_badname().
+ - Cleaned up setting/clearing IP_LOOKUP_PENDING bit.
+ - Removed storeEntryLocked() trap in storePurgeMem().
+ - Added storeCheckExpired().
+ - Removed storeWalkThrough() and removeOldEntry(), changed
+ storePurgeOld() to do the walking through instead.
