Inaccessible backend

[Malte Sussdorff]

Hello,

I am using NGINX as a load balancer in front of two aolserver  
webservers. This works perfectly, sadly the AOLserver sometimes has  
the problem that it just "hangs" until it gets restarted. So it is  
accepting the connection, but not returning anything back.

Now I am unsure with which parameters to play in the proxy setting to  
reflect this behavior and say "if the server does not send anything  
back in e.g. 15 seconds then go to the other server".

Furthermore, is there a possibility to have a different setting for  
specific locations, so that "mysite://longreportpage" has a timeout  
of 60 seconds?

Thanks for helping me out.

(from my proxy.conf)

proxy_connect_timeout      50;
proxy_send_timeout         50;
proxy_read_timeout         50;

proxy_buffer_size          4k;
proxy_buffers              4 32k;
proxy_busy_buffers_size    64k;
proxy_temp_file_write_size 64k;
