Hi,
I'm developing a webaccel project and I am trying to use apache to do that.
I'm choosing apache because squid does not support natively http/1.1
compression.
The main resources are: security (mod_security), saving bandwidth
(mod_deflate) and lowering backend servers load (mod_proxy/mod_disk_cache).
My testing environment is: one backend server, one webaccel server, two
windows workstation (1- firefox and 1- MSIE 6.x). All steps were right
(proxy, cache and deflate) but apache cached two copies of all objects for
every site I access- one for firefox and one for MSIE (I checked this on
headers stored in the cache directory)- When using other version of MSIE
(7.x) no more copies were done.
Is this a common apache (mod_cache) behaviour ? Does squid has this same
content negotiation ?
debian:/cache# grep 'fd.jpg?' * -r
