Fast 404 is a low foot-print plugin that quickly inspects an incoming HTTP request, and terminates the request as soon as possible if the request is for a non-existing resource. If the browser is expecting an HTML page (indicated by the
Accept HTTP header), this plugin will not intercept it. For all other requests, this plugin will terminate it immedaitely, saving server resources and bandwidth.
When a user browser requests a resource (such as a
jpg image, or a
.woff2 font file), the web server sends this resource if it is available in the requested location. If the file does not exist, the request is forwarded to WordPress to handle. Unless you are using a plugin that dynamically generates these files, these file-not-found requests trigger a full WordPress Page-Not-Found error page. This plugin inspects such incoming requests, and if the browser indicates that it is looking for a resource other than an HTML page, this plugin terminates the request as soon as possible to prevent WordPress from serving this request which would be a waste of resources and bandwidth. This plugin carefully makes sure that the short-circuited 404 pages (which just shows “Not Found” on a blank page) is only returned to browser asset requests, and not for end users who expect an HTML page.
By default, all HTTP requests to
js|css|jpg|jpeg|gif|png|webp|ico|exe|bin|dmg|woff|woff2 extensions will be fast 404’d. You can configure the extensions and even configure an exclusion pattern to prevent this plugin from intercepting certain requests.
This plugin is the WordPress port of phpwatch/fast404 package.

How to configure the error message?
This plugin ensures that the error message is not shown to end users who request URLs from the browser address bar. It is configured as “Not Found” by default.
However, you can override this message by adding a PHP constant to your
wp-config.phpfile. Anywhere in this file, put this:
define('FAST404_ERROR_MESSAGE', 'My new error message');
How to configure file types?
js|css|jpg|jpeg|gif|png|webp|ico|exe|bin|dmg|woff|woff2extensions are terminated early.
You need to define a PHP constant in
wp-config.phpfile to override this. The value of the constant MUST be a valid regular expression matched against the request URI.
How can I log requests?
You cannot. The whole point of this plugin is to save server resources when the request cannot be served. It takes the first opportunity to terminate the request, and it might be early in the page request-cycle that any of the logging functionality is even available yet.
