htaccess，如果没有query_string

Question

Is it possible to have something like.

IF ! ${QUERY_STRING} no-cache=1
<load mod_gzip>
END IF

I am trying to allow cache-busting across our dev environment if there is a query_string of no-cache=1

You can use this code in your root .htaccess:

# enable compression for all requests
SetOutputFilter DEFLATE

RewriteEngine On

# disable gzip compression is ?no-cache=1 is set in URL
RewriteCond %{QUERY_STRING} ^no-cache=1$ [NC]
RewriteRule ^ - [L,E=no-gzip:1,E=dont-vary:1]
