ZServer -> Apache/mod_proxy -> mod_gzip: Possible???
Hi everyone, I've searched high and low but I can't find any documentation for setting up mod_gzip to work with a Zope server (ZServer) being served through Apache's mod_proxy with the ProxyPass directives. Is this possible at the moment? Is there maybe a Zope product that handles gzipping served pages? This seems like a really good idea... I have mod_gzip working with Apache - other VirtualHosts on the same machine that aren't proxied serve gzipped pages - but apparently mod_proxy and mod_gzip don't like to play in the same sandbox. Other people have reported success using mod_rewrite instead... Is there some sort of performance hit you sustain in this case? If not, how do you set that up? =) thanks, Paul. -- Paul Horbal - ATIPS Web Manager horbal@atips.ca

HI Paul, I use mod_proxy + mod_gzip and it works great - if it weren't for the damn browsers ;-). Seriously, there can be some gotchas, but all encountered were client side problems. I use mod proxy, invoced via a rewrite rule (RewriteRule .... [P]) The only thing which might be special is mod_gzip_item_include handler proxy-server There are some examples on the mod_gzip homepage&mailing lists. cheers, oliver
Hi everyone... After following Oliver's advice and bumbling through the mod_gzip mailing list further, I've gotten mod_gzip to start compressing all the Zope stuff served through Apache.

Hi everyone...
After following Oliver's advice and bumbling through the mod_gzip mailing list further, I've gotten mod_gzip to start compressing all the Zope stuff served through Apache. Here's a listing of the entries in my httpd.conf for anybody else that would like to try it (I highly recommend it):
# In the main part of httpd.conf
mod_gzip_on Yes mod_gzip_can_negotiate Yes mod_gzip_add_header_count Yes mod_gzip_minimum_file_size 400 mod_gzip_maximum_file_size 0 mod_gzip_temp_dir /tmp mod_gzip_keep_workfiles No mod_gzip_maximum_inmem_size 100000 mod_gzip_dechunk Yes
mod_gzip_item_include mime ^text/* mod_gzip_item_include mime httpd/unix-directory mod_gzip_item_include file \.htm$ mod_gzip_item_include file \.html$ mod_gzip_item_include handler proxy-server mod_gzip_item_include handler cgi-script
mod_gzip_item_exclude rspheader Content-Type:image/* mod_gzip_item_exclude mime text/css mod_gzip_item_exclude file \.css$ mod_gzip_item_exclude file \.js$
# Now the VirtualHost for my Zope ZServer
<VirtualHost xxx.xxx.xxx.xxx> ServerName www.foo.com ServerAdmin me@foo.com

Note the salient features:
a) ...include mime ^text/* -- tells mod_gzip to look for any file with a mime type of "text" - this includes most stuff served up through Zope IIRC
b) ...include handler proxy-server -- reminds mod_gzip to try and intercept mod_proxy requests too (this is the part I was missing)
c) ...exclude rspheader Content-Type:image/* -- tells mod_gzip not to bother compressing images (the gain is minimal in most cases and actually chokes NS4 browsers)
