annotate src/mail/ngx_mail_pop3_module.h @ 8551:c35b255d80dc quic

HTTP/3: close connection on keepalive_requests * 2. After receiving GOAWAY, client is not supposed to create new streams. However, until client reads this frame, we allow it to create new streams, which are gracefully rejected. To prevent client from abusing this algorithm, a new limit is introduced. Upon reaching keepalive_requests * 2, server now closes the entire QUIC connection claiming excessive load.
