waf file-compress-rule

config : waf file-compress-rule

Use this command to compress specific file types in HTTP replies.

Compression can reduce bandwidth, which can reduce delivery time to end users. Modern browsers automatically decompress files before they display web pages.

You can configure most web servers to compress files when they respond to a request. However, if you do not want to configure each of your web servers separately, or if you want to offload compression for performance reasons, you can configure FortiWeb to do the compression.

By default, the maximum pre-compressed file size is 64 KB. FortiWeb transmits files larger than the maximum without compression. You can use the config system advanced command’s max-cache-size setting to adjust the maximum files size (see “config system advanced”).

To exclude specific URLs from compression, see “config waf exclude-url”.

To apply a compression rule, select it in an inline protection profile. See “config waf web-protection-profile inline-protection”.

To use this command, your administrator account’s access control profile must have either w or rw permission to the wafgrp area. For more information, see “Permissions”.
