| Reference: | client_header_buffer_size |
Directive sets the headerbuffer size for the request header from client.
For the overwhelming majority of requests it is completely sufficient with a buffer size of 1K.
However if a big cookie is in the request-header or the request has come from a wap-client the header can not be placed in 1K, therefore, the request-header or a line of request-header is not located completely in this buffer nginx allocate a bigger buffer, the size of the bigger buffer can be set with the instruction large_client_header_buffers.
