The compression is enabled

Two modules to open with deflate

LoadModule Deflate_module modules/mod_deflate.so

LoadModule Headers_module modules/mod_headers.so

The compression ratio can be set 1-9 recommended not too high otherwise it will consume too much CPU

Use DOS to install modules that are not available

Apxs-c-i-a/GAO/HTTPD-2.4.23/MODULES/METADATA/MOD_HEADERS.C

I perform the installation

A automatically adds a loadmodule to the httpd.conf to use the module

C Perform a compilation operation

Configuration items, written directly in HTTP, can be

<ifmodule mod_deflate.c>
