I'm trying out this software FirePHP which is an out-of-band error
logging that works with PHP and Firebug.
With nginx setup as a load balancer, whenever large headers are being
passed back (from FirePHP) it causes nginx to send back a 502 Bad
Gateway message.
Here are the headers being sent (I received these by going around the
load balancer directly to the web server behind nginx).

If you use proxying, then try something like proxy_buffer_size 16k; # this is for header and first body part proxy_buffers 4 16k;

If I set this to a very large value, such as 128k does it allocate this
for every connection or only as needed?ลก This really only needs to be
large for debugging purposes.<br>
