I have a CSP page that throw a "414 error - Request-URI Too Long" when I put lot of text (eg : 10000 characters) into a field of a submitted form. The form is submitted using POST method.
Based on some experiments I made, it seems the max size of a URL is around 8200 characters.
What is the official limit, and is there a way to increase it ? I searched in the documentation but couldn't find anything.
