Hi,

Is there a way to provide fallback URL when HTTP redirect times out? What I'm trying to achieve is that when I hit the original url, I would respond with HTTP redirect (300, 307?) giving the browser new URL and the fallback URL in case the new URL times out?

I was also considering doing this client side but it just does not seem to be very effective (in terms of speed, client support). What I would do is probably have a tiny 1x1px image on each server, try loading it and then check with javascript which server is up and redirect there.

Any other ideas? Thanks
