Hello!
I am new with nginx and learning it for now :), I need some help with set proxy_send_timeout, I need to set this only if url has 'stime' in proxy here is what I am doing:

if ($arg_stime != ""){
proxy_send_timeout 15;
proxy_read_timeout 15;
}
but nginx does not start and gives following error:

4901#0: "proxy_send_timeout" directive is not allowed here in default.conf

any suggestions, Thank you

Best regards

Sajid
