I'm trying to use a single HAProxy instance to handle multiple, different websites, which is what I was trying to achieve with the backend / frontend setup. I ended up using different IP addresses instead, which works great. Ah, no worries. :)

Unfortunately I am running into some issues when I try to replicate this setup. My HAProxy config works great with a single website and a corresponding listen statement. But when I try to set up two websites by using a backend for each as well as a single frontend, switching between them using a url_sub acl very similar to your example, I keep getting 503 errors when I try to hit either of the websites. Have you ever come across anything like this? Thanks for the write-up!
