mod_deflate

mod_deflate is a modified version of
mod_compress. mod_deflate can compress any output from lighttpd static or
dynamic. It doesn't support caching compressed output like mod_compress.
mod_deflate is included in 1.5.0, see How to Install section below to use
it with 1.4.x

Module options: {{{
deflate.enabled = "enable"
deflate.compression-level = 9
deflate.mem-level = 9
deflate.window-size = 15
deflate.bzip2 = "enable"
deflate.min-compress-size = 200
#deflate.sync-flush = "enable"
#deflate.output-buffer-size = 8192
deflate.work-block-size = 512
deflate.mimetypes = ("text/html", "text/plain")
#deflate.debug = "enable"
}}}

The sync-flush option allows dynamic scripts to flush output to the browser
and still use compression.
work-block-size is the number of kilobytes to compress at one time, it allows
the webserver to do other work (network I/O) in between compression.
min-compress-size is the smallest response size that will be compressed.

output-buffer-size is a per connection buffer for compressed output, it can
help decrease the response size(fewer chunks to encode). If it is set to
zero or if sync-flush is enabled a shared buffer will be used.

=== How to install for lighttpd 1.4.x ===
First download the patch (download links below) and place the patch outside of the lighttpd-1.4.xx folder, then run: {{{
patch -p0 < lighttpd-1.4.xx-mod_deflate.diff
}}}
This will patch your lighttpd-1.4.xx directory's files. Remember to change xx to the version number you are using.

Then: {{{
cd lighttpd-1.4.11
rm -f src/Makefile.in src/Makefile
automake
./configure --with-bzip2
make
make install
}}}

Place mod_deflate after mod_rewrite in the server.modules array in the lighttpd configuration file and enter in the mod_deflate configuration options. Remember to also enable bzip2 with the --with-bzip2 flag while doing the configure.
