Ngnix Server

In most situations, websites running with Ngnix running as a proxy to Apache are compatible with Pegasaas.  There is a rare known case when the size of the web page can exceed the size of buffer allowed by Ngnix.  In these situations, you will get a 500 server error when viewing the web page on the front end.  The only known solution is to increase the buffer size in ngnix by adding the following directives:

fastcgi_buffers 16 16k;
fastcgi_buffer_size 32k;
proxy_buffer_size 128k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;
