Description

Redirects slow response time while using unnecessary resources. Therefore, they should be avoided as much as possible. Redirects can occur at different places: HTML code, JavaScript code, HTTP server, and application server (PHP, etc.).

Example

On the HTTP server level (Apache, in this case), redirects involve activating systematic URL rewriting via the .htaccess file:

<IfModule mod_alias.c>
    Redirect permanent http://old_address.com http://new.address.com/
</IfModule>

It is preferable to manually replace static addresses embedded in web pages.

Validation rule

The number of ... is equal to or less than
