Visiting a site on your browser could return the request header or cookie too large error message. You already know that cookies are small bits of data that your browser stores locally.
They’re used for authentication and tracking purposes, but if they exceed a certain limit, they can make accessing a website impossible. Here’s how to resolve this issue.
What does 400 request header or cookie too large mean?
A request header or cookie too large error appears when you attempt to open a given website, but instead of bringing up the expected content, it brings up this error.
This indicates that the server is refusing to fulfill your request because the request header size has exceeded the capacity limits of either the server or the software that runs it.
The exact size of the limit depends on the server’s configuration and operating system.
There are several reasons why this can happen:
- Corrupt cookies – Unfortunately, cookies can sometimes cause problems in browsers. They may become corrupted if your browser crashes or gets infected with malware.
- Cookie size is too large – If you’re receiving the request header or cookie too large error, it means that the cookies set by the site you’re trying to visit have gotten too large.
- Website limitations – Some websites have a limit to how much data they can accept in one request. This is often due to security concerns and/or limitations on their network infrastructure.
- Outdated/corrupt add-ons – Extensions can sometimes cause problems when connecting to websites.
- Server issues – Sometimes, it’s an issue with a particular server and the websites linked to it. You may get a 400 request header or cookie too large nginx error because it may be overloaded with traffic and cannot handle all requests simultaneously.
