Changes with Apache 1.3.23
+ *) mod_proxy changes:
+
+ *) Bug fix for ap_proxy_cache_conditional(), unititialized wetag
+ [Zvi Har'El <rl@math.technion.ac.il>]
+
+ *) Add persistent connection handling
+ The patch changes mod_proxy to write the reply-headers using
+ ap_send_http_header() instead of directly using ap_bvputs(). This not
+ only simplifies mod_proxy, in my opinion at least, but enables it to
+ make use of the features of Apache's normal header and persistent
+ connection machinery.
+ [Christian von Roques <roques@mti.ag>]
+
+ *) Graham Leggett's original 1.3.12 patch, updated for 1.3.19+

+ [Graham Leggett <minfrin@sharp.fm>]
