How to allow GET requests larger than 5400 bytes in nginx?

Question

Nginx

When the total query + all headers exceed approximately 5400 bytes, nginx does not return a response and the connection is closed (it does not even give an error).
Tried:

• client_header_buffer_size 32k;
  
• large_client_header_buffers 4 64k;
  
• client_max_body_size 1m;
  
• client_body_buffer_size 1m;
  
• annotate the use of $args
  

Nothing helps. There is no backend, a static html file is given. Nobody knows the reason? Or is it the browser itself limiting?
PS. Advising POST - I know what POST is for, and what GET is for. In my case, this is a search query string that must be present in the URL so that the user can copy and save this link. POST won't work here.

Answer 1

Do not look for a problem out of the blue, use POST which is intended for this

Answer 2

Look at here. I have not tried to configure it myself.
