Subject Compression and SSL
Date Mon, 02 Nov 2009 16:48:17 GMT
OK, another newbie-ish question here.


I am using Tomcat 5.5.x with APR/native libraries on Windows 2003 x32 or
Windows 2008 x64 to serve applications from the US to Asia-based

We encrypt everything using SSL, from Login page onward, with
<transport-guarantee> of CONFIDENTIAL. 

All URLs are configured as relative, i.e., "/images/picture.png",
"/APP1?param1=value....", etc.

We use Tomcat as the web server with no intervening proxies,
load-balancers, accelerators, etc.

Response time is noticeably slow (based on complaint level) and I am
looking for ways to improve it.

Will setting the HTTPS connector "compression=on" actually compress the
data for HTTPS?

Does it compress before or after applying the encryption?


And,  in case it's relevant, here is the relevant excerpt from the
web.xml file we use:
















Any assistance would be much appreciated.
