Re: Using GZip compression for js files in Ecommerce module

[Pierre Smits]

Hi all,

I don't know having this in OFBiz affects performance when OFBiz is behind
a webserver (like Apache HTTP) via normal proxy processes or via ajp, which
are standard scenarios in in a multi-tier, high availability/failover setup.

You can also use mod_proxy + mod_deflate to do that but why do it since it's already included in OFBiz (same with nginx, etc.)?
So no, I don't think it adds any performance impact  if you don't use mod_deflate and I believe it should be very minor if ever you
do it twice (but again don't do it ;o)

Mmm.. finally this is wrong. Because if you use ajp then you bypass http/s connectors and you should handle compression using
mod_proxy + mod_deflate in HTTPD

Sorry for the confusion

Note: this is out of OFBiz scope

Note that, if you use something else than AJP (nginx with haproxy for instance) you will still use Tomcat HTTP connectors hence
internal OFBiz compression...

I have added text/javascript,text/css as new compressableMimeTypes at r1310975

What about adding <property compressionMinSize="2048"/>?
It needs only to change XSD it seems, but what about the size?
