服务器接口优化

1. 缓存：

Apache的httpd.conf中，加载对应模块LoadModule expires_module modules/mod_expires.so，然后添加以下设置：

ExpiresActive On
ExpiresDefault "access plus 1 hour"

数据有效期为1小时。

2. Gzip压缩：

Apache的httpd.conf中，加载对应模块LoadModule deflate_module modules/mod_deflate.so，然后添加以下设置：

# 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
