Description

Long URLs appear to be broken with HTTP2. The threshold I've observed when things are broken with Chrome and Firefox is 5047byte URLs (with 24 chars of https and hostname). These URLs work properly with http 1.1 (plain http and https) but with http2 enabled nginx consistently returns a 400 for long urls.

While testing the following (aggressively permissive) buffer settings are defined at the server block level.

client_header_buffer_size 64k;
large_client_header_buffers 4 32k;
proxy_buffer_size 128k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;

For example my URLs include base64 encoded json (JWT) data:

Does it work with 64k in large_client_header_buffers?

client_header_buffer_size 64k;
