在apache中開啟deflate方法的總結

1.在httpd.conf裡面的站點配置裡增加如下內容：
AddOutputFilterByType DEFLATE text/html text/plain text/css text/xml text/javascript
DeflateCompressionLevel 9
 
SetOutputFilter DEFLATE
 
 
 
 
2. 在.htaccess，增加以下的內容：
 
<IfModule mod_deflate.c> 
 
############################################ 
## enable apache served files compression 
## http://developer.yahoo.com/performance/rules.html#gzip 
 
    # Insert filter on all content 
    ###SetOutputFilter DEFLATE 
    # Insert filter on selected content types only 
    AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript 
    DeflateCompressionLevel 9 
    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 
 
    # 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 
 
</IfModule> 
<IfModule mod_deflate.c>

當項目已經上線後優化apache就使用使用第二種方法，因為不用重啟apache服務器。
