[…skipped awfull really long uri, which probably will be just

Have you tried using POST method instead? Looks like RFC 2616
mentions your case explicitly:

% 10.4.15 414 Request-URI Too Long
%
% The server is refusing to service the request because the
Request-URI
% is longer than the server is willing to interpret. This rare
% condition is only likely to occur when a client has improperly
% converted a POST request to a GET request with long query
% information, when the client has descended into a URI “black hole”
of
% redirection (e.g., a redirected URI prefix that points to a suffix
of
% itself), or when the server is under attack by a client attempting
to
% exploit security holes present in some servers using fixed-length
% buffers for reading or manipulating the Request-URI.

Note the “has improperly converted …” part.

Also, try putting the query string into the request body…

Do you show complete URL ? It takes about 7200 bytes, so 8k
client_header_buffer_size should be enough for it.
