This article introduces the relevant knowledge of "the configuration of Nginx data compression". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Nginx data compression configuration:

Add the following configuration items to the http module of Nginx's nginx.conf file

# gzip Compression feature configuration

Gzipon

Gzip_min_length2k

Gzip_buffers4 16k

Gzip_http_version1.0

Gzip_comp_level6

Gzip_proxiedany

Gzip_typestext/css text/xml image/gif image/jpeg image/png application/javascriptimage/x-ms-bmp application/pdf text/plain application/jsonapplication/xhtml+xml

Gzip_vary on

Gzip_disable "MSIE [1-6]."

Configuration item description:

Gzip: decide whether to turn on the gzip module

Param:on | off

Example:gzipon

Gzip_buffers: sets the gzip request memory size, which is used to apply for memory space in multiples of the block size.

Param1:int

The unit after param2:int (k) is k.

Example: gzip_buffers 4 8k

Gzip_comp_level: set the gzip compression level. The lower the compression level, the faster the compression speed, the smaller the file compression ratio, and vice versa, the slower the speed, the greater the file compression ratio.

Param:1-9

Example:gzip_com_level 6

Gzip_min_length: when the returned content is greater than this value, gzip is used to compress. When the value is 0, all pages are compressed.

Param:int

Example:gzip_min_length 1000

Gzip_http_version: used to identify the version of the http protocol. Early browsers do not support gzip compression, and users will see garbled code, so this option is added to support the previous version, and this item can be ignored at present.

Param: 1.0 | 1.1

Example:gzip_http_version 1.0

Gzip_types: sets the MIME type to be compressed. Non-set values do not compress.

Param:text/html | application/x-javascript | text/css | application/xml

Example:gzip_types text/html

Gzip_proxied: enabled when Nginx is used as a reverse proxy

Param:off | expired | no-cache | no-sotre | private | no_last_modified | no_etag | auth | any

Expample:gzip_proxiedno-cache

Off-turn off all agent result data compression

Expired-enables compression if the header contains "Expires" header information

No-cache-enables compression if the header contains "Cache-Control:no-cache" header information

No-store-enables compression if the header contains "Cache-Control:no-store" header information

Private-enables compression if the header contains "Cache-Control:private" header information

No_last_modified-enables compression if the header contains "Last_Modified" header information

No_etag-enables compression if the header contains "ETag" header information

Auth-enables compression if the header contains "Authorization" header information

Any-unconditionally compress all result data

Gzip_vary: add the http header information Vary: Accept-Encoding to the back-end proxy server to identify whether gzip compression is enabled.

Param:on | off

Expample:gzip_varyon

Gzip_disable: close Gzip according to the "User-Agent" header, using regular expressions.

Param:regex (regular expression)

Example:gzip_disable "MSIE [1-6]."
