Wouldn't it be scary for people running webservers that get millions of requests a day to use this version?

Friday, August 4. 2006mod_deflate for Apache 1.3.37
A new Apache 1.3.37 is out and I had to upgrade all my servers to it, in the process I've had to compile mod_deflate, a high performance compression module that works MUCH faster then mod_gzip. This is primarily thanks to the fact it does not use temporary files, but instead does everything in memory. Since the official mod_deflate package has been abandoned by its author, even though the code still works with a few minor tweaks. So, I've decided to post a patched version of this module for all interested Apache 1.3.37 users.
You can download it here: http://ilia.ws/uploads/patches/mod_deflate-1.0.21i.tar.bz2 MD5: 4bd8b6773d9cb843494faceae3c9c945 The package also includes a short README files that explains how to install this module on your server. For people too lazy to read the README, the instructions follow at the bottom of this blog entry  .
Installing mod_deflate
-------------------------------------------------------------------------- 1) Apply mod_defalte.patch on top of Apache 1.3.37 2) copy mod_defalte.c into the src/modules/extra directory 3) Add --activate-module=src/modules/extra/mod_deflate.o to your configure At this point you can proceed with the regular Apache installation. # To enable mod_deflate you need to add "DeflateEnable On" to you httpd.conf DeflateEnable On # Minimum size of the content to compress DeflateMinLength 3000 # Compression ration (1 best performance & smallest compression) (9 worst # performance and best compression) DeflateCompLevel 5 # Don't try to compress proxied content. DeflateProxied Off # Minimum HTTP version necessary to enable compression DeflateHTTP 1.0 # This setting allows you to avoid compressing content for browser that do # not support it DeflateDisableRange "MSIE 4." # Unfortunately mod_defalte does not support masks such as text/* so you # need to explicitly identify all of the mime types you wish to compress. DeflateTypes text/plain DeflateTypes text/html DeflateTypes application/xml DeflateTypes application/x-javascript DeflateTypes httpd/unix-directory DeflateTypes text/xml DeflateTypes text/css Comments

Why? php.net main mirror uses it and it is accessed by a fairly large number of users last I checked
. I've also deployed on at least 5-6 different sites with few hundred sites running and so far no problems.
Shawn on :
I've used mod_deflate before, and found it quite a useful tool.
The author also created mod_accel, which is like mod_proxy on crack; it does almost everything, incluing not proxying specific files that match given regex. I know I'm not up to the task, but I wonder how difficult it would be to convert this into a module - despite the fact that it patches itself directly into the tree. If you use Dean's Apache 1.3 time() scoreboard patch, and -DBUFERED_LOGS, you'll see even more of a performance increase: http://arctic.org/~dean/apache/1.3/ (Of course, this makes upgrading a royal pain.. )
Eric on :
I can not see any mode_deflate information from http header.
only Server: Apache/1.3.37 (Unix) mod_fastcgi/2.4.6 mod_deflate/1.0.21 how can I fix it? Ilia Alshanetsky on :
You add mod_deflate config params inside your httpd.conf
