AW: Problem caching with Apache 2.2 mod_proxy

FYI: The code snippet refers to a former Apacher version:
http://httpd.apache.org/docs/1.3/mod/mod_proxy.html 

If creation of cached file works, maybe Apache does not get the right cache
header info from Zope (DTML-Template headCache). Maybe the pragma-Parameter
is set wrong. Please check the http cache header via the Zope Port 8080
(without Apache). For cache header analysis I recommend firefox
webdevelopers plugin or Microsoft Fiddler.

PS:
If you have got the mod_proxy directive successfully tested for Apache 2.2
please send it to the forum; I will extend the "howto" document.
