Nginx Bad Request error

In nginx.conf, both Client_header_buffer_size and large_client_header_buffers are adjusted to alleviate this problem.

The main configuration is client_header_buffer_size this, the default is 1k, so the header is less than 1k will not be the problem.
As I now configure is:
Client_header_buffer_size 16k;

Large_client_header_buffers 4 64k;

It is important to note that Large_client_header_buffers 4 This 4 is not a numerical size .

The above describes the Nginx bad request error, including the aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
