Is your feature related to a problem? Please describe.

I’m working on an application that needs to deal with large http headers, but I’m getting the following exception:

WARNING:  Invalid HTTP request received.
Traceback (most recent call last):
  File "/usr/local/lib/python3.9/site-packages/uvicorn/protocols/http/h11_impl.py", line 136, in handle_events
    event = self.conn.next_event()
  File "/usr/local/lib/python3.9/site-packages/h11/_connection.py", line 432, in next_event
    raise RemoteProtocolError(
h11._util.RemoteProtocolError: Receive buffer too long

Describe the solution you would like.

This error could be fixed if I was able to configure the max_incomplete_event_size of the h11 connection:

https://github.com/python-hyper/h11/blob/master/h11/_connection.py#L119

Describe alternatives you considered

For the time being, I’ve moved to Hypercorn which does allow me to change that parameter.

Be aware that I’d need to study this issue again, so it’s not a promise of merging it. But if you work on the PR, I’ll try my best to follow up.

I can review it if you continue the previous implementation. I’ve written some comments over there.
