You could:

1. Resolve the IP from the host of the page
2. Try to connect to port 80 on the resolved IP using plain sockets

This is a bit low level however and will add complexity since you will need to make a simple GET request through the socket. Then validate the response so you're sure that its actually a HTTP server running on port 80.
