When a site creates way too many cookies, you get a “Bad Request – Request Too Long”

Posted by jpluimers on 2018/05/09

I a while ago, I had this error:

Bad Request – Request Too Long


HTTP Error 400. The size of the request headers is too long.

It happened because over time, Microsoft had managed to store 100+ cookies data locally, making the request some 8k in size. Which they could not handle.

Bad Request - Request Too Long HTTP Error 400. The size of the request headers is too long.

Bad Request – Request Too Long HTTP Error 400. The size of the request headers is too long.
