Hi,

What is the relationship between these three directives - proxy_busy_buffers_size, proxy_buffers and proxy_buffer_size?
Currently, I'm only using proxy_buffer_size in my location block but whenever I set it to some higher number, for ex: 32k, it throws the following error -
nginx: [emerg] "proxy_busy_buffers_size" must be less than the size of all "proxy_buffers" minus one buffer

Thanks in advance!
