What is the Ignore_Invalid_Headers Directive?

The Ignore_Invalid_Headers Directive is a directive in Nginx that specifies whether or not it should ignore any invalid headers sent by the browser. This directive is used to prevent an attack known as HTTP Request Smuggling, where an attacker attempts to trick the server into processing an invalid request. This is generally done by sending two different requests with invalid headers, such as one with a “Content-length” header and one without. If the server is not configured to ignore invalid headers, then the server will mistakenly process both requests.

Where is the Ignore_Invalid_Headers Directive Used in NGINX?

The Ignore_Invalid_Headers Directive in Nginx is generally used in two main places. The first is in the main block, outside of any server blocks. This will set a global setting that will apply to all servers. The second is in individual server blocks, which will override any global setting. This is useful in cases where you want to enable Ignore_Invalid_Headers for some servers but not others.

How do you Configure the Ignore_Invalid_Headers Directive in Nginx?

The Ignore_Invalid_Headers Directive in Nginx is configured using a simple on/off setup. To enable the directive, use the following code:

To disable the directive, use the following code:

ignore_invalid_headers off;
