Why am I getting a “412 Precondition Failed” from a website?

Applies to: Grid System

The most likely cause of this response is a mod_security settings. The mod_security module will send this response when a portion of the web request data that one of our servers received is likely to be malicious.

If it is necessary to disable this protective feature you can do this using a .htaccess directive:

SecFilterEngine Off

Please Note: This will disable mod_security for the directory that the .htaccess file is located in, and the subdirectories below the .htaccess file. If you wish to enable it for subdirectories you can do so by using the following .htaccess directive:

SecFilterEngine On
