compress components with gzip(压缩传输)

本文使用的是 httpd-2.0.59 使用mod_gzip 和mod_deflate两个模块均未成功完成 gzip compress功能，重新编译apache 添加--enable-deflate模块，配置httpd.conf添加如下几段请参考下面的那段设置仅仅压缩了text、xml、html，如果还有其它复杂的请参考apache官方网站。
The following configuration, while resulting in more compressed content, is also much more complicated. Do not use this unless you fully understand all the configuration details.

for compress (apache) evreyting excepet images

# modified by boean
# for compress everything excepet images
# Insert filter
SetOutputFilter DEFLATE

# Netscape 4.x has some problems...
BrowserMatch ^Mozilla/4 gzip-only-text/html

# Netscape 4.06-4.08 have some more problems
BrowserMatch ^Mozilla/4\.0[678] no-gzip

# MSIE masquerades as Netscape, but it is fine
# BrowserMatch \bMSIE !no-gzip !gzip-only-text/html

# NOTE: Due to a bug in mod_setenvif up to Apache 2.0.48
# the above regex won't work. You can use the following
# workaround to get the desired effect:
BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html

# Don't compress images
SetEnvIfNoCase Request_URI \
\.(?:gif|jpe?g|png)$ no-gzip dont-vary

# Make sure proxies don't deliver the wrong content
Header append Vary User-Agent env=!dont-vary
