In order to implement a DNS-based failover scheme, I need a way to fetch a web page from a server whose IP address is not listed in an A-record for the domain name (the backup server).
I have tried a number of approaches using LWP, including Direct a LWP connection to a different host, but have not found any that work reliably. Can anyone show how to do this? I would think that I should be able to use the IP address in the URL (http://1.2.3.4/) and force a Host header in a LWP request somehow, but after looking at the LWP documentation and trying several different approach, I've not come up with anything that works. Any help will be greatly appreciated. In reply to LWP - test website at multiple IPs by mp
