Apache turns on GZIP to compress web pages_PHP tutorial

2. Web server processing

By looking at the HTTP header, we can quickly determine whether the client browser used supports gzip compression.

If the following information appears in the sent HTTP header, it means that your browser supports the corresponding gzip compression:

# mod_gzip

<span <</span><span ifModule </span><span mod_gzip.c</span><span ></span><span 

mod_gzip_on Yes

mod_gzip_dechunk Yes

mod_gzip_item_include file \.(html?|txt|css|js|php|pl)$

mod_gzip_item_include handler ^cgi-script$

mod_gzip_item_include mime ^text/.*

mod_gzip_item_include mime ^application/x-javascript.*

mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*

</span><span <</span><span ifModule</span><span ></span>

(1) Strictly match file types

# mod_deflate：

<span <</span><span ifmodule </span><span mod_deflate.c</span><span ></span><span 

DeflateCompressionLevel 6 #压缩率, 6是建议值.
