Syntax: client_body_buffer_size size;
Default:
client_body_buffer_size 8k|16k;
Context: http, server, location
Sets buffer size for reading client request body. In case the request body is larger than the buffer, the whole body or only its part is written to a temporary file. By default, buffer size is equal to two memory pages. This is 8K on x86, other 32-bit platforms, and x86-64. It is usually 16K on other 64-bit platforms.
