So we need to disallow BING from specific pages, all which begin with "ourdomain.com/Merchant2/*"
That part should hopefully be easy, although I have heard BING does not respect robots.txt and that it needs to be done on the NGINX level of our server.
(2) The other problem may be related to this:
Usually when I submit an order through our shopping cart, it takes 3-5 seconds to process, which is normal.
... But about 1 out of 7 times, it takes a long time, maybe over 30 seconds for our shopping cart to communicate back the ORDER CONFIRMATION PAGE and we get a NGINX 504 GATEWAY TIEMOUT.
The order still goes through our credit card processor, but our shopping cart does not display the "order confirmation page" because of the 504 error.
... But we want to fix the BING problem by disallowing from that specific URL string (we want Bing to still crawl the rest of our site)
We also want to increase the TIME-OUT time to perhaps 180 seconds or so at the NGINX level to see if that helps, because right now it is timing out at 30 seconds and causing the 504 error.
