Proxy buffering query

[libresco_27]

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!
