如何在apache2上做gzip压缩配置？

#LoadModule headers_module modules/mod_headers.so
#LoadModule deflate_module modules/mod_deflate.so

LoadModule headers_module modules/mod_headers.so
LoadModule deflate_module modules/mod_deflate.so

<IfModule mod_deflate.c>
<Location />
#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 2.0.59
# the above regex won’t work. You can use the following
# workaround to get the desired effect:
# BrowserMatch \bMSIE !no-gzip !gzip-only-text/html force-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html

# Don’t compress images and other
#SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary
#SetEnvIfNoCase Request_URI .(?:exe|t?gz|zip|bz2|sit|rar)$ no-gzip dont-vary
#SetEnvIfNoCase Request_URI .(?:pdf|doc)$ no-gzip dont-vary

AddOutputFilterByType DEFLATE text/html text/css image/gif image/jpeg image/png  application/x-javascript
# Make sure proxies don’t deliver the wrong content
Header append Vary User-Agent env=!dont-vary

#DeflateFilterNote ratio ratio_info
#LogFormat '"%v %h %l %u %t “%r" %>s %b "%{Referer}i" "%{User-Agent}i"" (%{ratio}n)' deflate
