Suppose I have a website that is normally accessed at address www.mywebsite.com.
Now let's say the website is down completely (think server has melted). I want the users trying to reach www.mywebsite.com to end up on a maintenance URL on another server instead of having a 404.
Is this possible easily without having to route all the trafic through a dispatcher/load balancer?
I could imagine something like :
When the default server is UP traffic is like :
[USER]<---->[www.mywebsite.com]<---->[DISPATCHER]<---->[DEFAULT SERVER]
When the default server is DOWN traffic is like :
[USER]<---->[www.mywebsite.com]<---->[DISPATCHER]<---->[MAINTENANCE SERVER]
Where [DISPATCHER] figures out where to route the traffic. Problem is that in this scenario all the traffic goes through [DISPATCHER]. Can I make it so that the first connection goes through dispatcher, and then, if the default server is up, the traffic goes directly from the user to the default server? (with a check every 10 - 15 minutes for example)
[USER]<---->[www.mywebsite.com]<-------->[DEFAULT SERVER] after the first successful connection
Thanks in advance!
