The controversial topic of a gzip content compression module for Apache 2.0 was brought
up this week and discussion on the development list soon descended
into a vitriolic flamewar, ranging from whether many or few
modules should be distributed with Apache, down to personal abuse
between list members.
The HTTP/1.1 specification describes how an HTTP client indicates that it can handle compressed
content by sending an Accept-Encoding header with each
request. The server may then choose to compress the response using
one of the compression schemes which the client claimed to support.
The mod_gzip module produced by HyperSpace
Communications adds support for the gzip compression scheme to Apache
1.3. This week a mod_gz module was independently
contributed, which implements a gzip compression filter for Apache
2.0, providing similar functionality to mod_gzip. One
important difference between the two modules is that
mod_gzip includes its own gzip implementation, whereas
mod_gz relies on an external zlib library.
The authors of mod_gzip indicated that a 2.0 port of
their code was under development, but would not be publicly released
until the next 2.0 beta release. After a heated debate comprising
of over a hundred messages, it was made clear that
mod_gzip would not be submitted for inclusion in
2.0. Despite this, a consensus has not yet emerged on whether
mod_gz will be included in 2.0.
It has been a couple of months since we last reported on new
figures from the Netcraft and E-Soft
surveys of web sites. Netcraft find that Apache and servers
based on Apache have just under 60% market share, and E-Soft
report just over 61%. In the secure server space, E-Soft find
little difference with Apache and Stronghold together having
61% market share.
The E-Soft report goes into a lot of interesting detail, showing
information such as the versions of servers being used and most
popular modules. We found it interesting that nearly 100 thousand
sites are still reporting they are running on Apache 1.2 (
Apache 1.3 was released over three years ago). The
most popular Apache module is still PHP, available on nearly half
of all Apache sites.
In this section we highlight some of the articles on the web that are of
interest to Apache users.
PHPBuilder take a look at
"using Webalizer to analyze Apache logs".
Webalizer is a freely available log analysis tool written in C that is
designed for speed; even
on a modest machine it can handle tens of thousands of log lines
a second. However it can
be tricky to get Webalizer installed, so this article takes you
step by step through how to get it installed and running.
Joe "Zonker" Brockmeier walks you through ways of improving your
Apache performance in
Benchmarking, Part 3". The article focusses on Linux systems, looking
at tuning both your hardware, server configuration, and modules.
