How to limit the size of request headers? #3696

|
Some malicious requests from scripts have very huge header sizes. How to set a limit or check these header sizes? It would be great to quickly end the TCP connection and get the IP address to add it to an IP block list. |

The limit that currently exists is the max_buf_size. If headers are not "complete" within the max size, then an error is returned and the connection closed. A potential new builder option is planned that would allow setting a header size limit smaller than the max buf size, but does not exist at the moment. |
