Conditional Rule Example

This article is a basic example of a Conditional EdgeRule, aimed at helping you understand the core functionality of using Conditionals with your rules.

The EdgeRules feature is available only on Enterprise plans.

Example: Defining Caching Behavior for Specific File Types

This rule prevents caching if the file extension ends with .css or .js and the http method is either GET or HEAD. Notice that we have to use variables to accomplish this behavior.

Example of the Rule

    location ~ \.(?:css|js)$ {
    set $no_cache 0
    if ($http_method ~ (GET|HEAD)) {
    set $no_cache 1;
    }
    ...
    proxy_no_cache $no_cache;
    ...
    }
