mod_perl SSL compression: Apache-Dynazip vs mod_gzip?

[Nigel Hamilton <ni...@turbo10.com>]

Hi,

	I've been using mod_gzip for the last 18 months and it has worked 
really well for dynamic pages and static content.

	However, recently I've needed to use SSL, but I've heard the 
combination of mod_gzip and SSL is buggy on some browsers.

	I've checked out Apache::DynaGzip and it looks like what I need - 
but I'm interested in what other SSL+Compression combinations work best 
with mod_perl?

	So here's a little survey ...

1. 	Are you using http compression with mod_perl?
2. 	Which compression modules? filters? are you using?
3.	Do you also compress SSL content?
4.	Do you get bizarre errors on some browsers?
5.	Do your pages contain CSS files and .js files?
6.	Recommendations?	


	Here is a url that discusses compression options:

You are right, there are some known issues about M$IE, which sometimes drops
first 2K bytes, when the user "refreshes" content over SSL. The way to work
around is the same for all compression approaches: just place 2K blank
spaces in the beginning of every your web page (fortunately, they will be
compressed very effectively).

There are no compression features for SSL on server side. Just the
encryption should be done over the (dynamically) compressed file/stream.
Apache::Dynagzip could be really helpful if you use mod_perl-enabled Apache
to generate content on-the-fly (see Web Content Compression FAQ, attached in
M$ Word format).

I like it.

Thanks,
