Redirect or Reverse Proxy or ??
I'm extremely new to the F5 community and fairly new to NLB in general..
I've got a secure web site live at one datacenter https://www.mine.com and we'll be moving this to a new data center behind an LTM and getting a new external IP. We have a 99% uptime SLA on this site.
Rather than dealing with DNS propagation and using a forwarder at the existing/old site post cut over. I was told by a coworker that we could do a relay or redirect at the new site with a web server and possibly with the F5 LTM allowing us to update the DNS record at any point prior to the cutover.
I was hoping someone here could help direct me not only with the correct terminology for this technology, but if and how it would work with the LTM.
My coworker calls it a relay, I've asked my dev guys and they're only familiar with redirects..
We need the host header to remain the same to prevent certificate issues prior to the cut over and to make the transition as seamless as possible with 0 downtime.
Thanks in advance..
