RE: [squid-users] Bypass Squid

I guess I'm looking for a way for the Squid server to check that port 80
and 443 are being accepted. If for some reason they are not, I'd like
traffic to just be forwarded to the backend server. What ways could
this be done?

I'm wondering how I could redirect the client request to the back end
server
if Squid stopped working for some reason. This would be while squid was
in
reverse proxy mode and we would not have access to the clients. Any
thoughts on if this could be done?

A public DNS record has an entry saying 12.12.12.12 is what yoursite.com
resolves to. Squid (at 12.12.12.12) is saying traffic coming in to
yoursite.com should really go to 10.10.10.10, on your back-end network.
Squid goes down and it is just like your webserver goes down. What
happens
if your webserver goes down and your clients don't have access to it?

Ie: your webserver is critical, so there are two of them, for
redundancy/failover. If your webserver is that critical, then your
infrastructure to it should be just as redundant so you don't have a
single
point of failure. In that case, having two squid boxes set up for
failover
would do the trick.

OR...call the person who manages DNS for you and have them change the IP
address to wherever your website can be reached.

OR..unplug squid and let traffic through to the back end
webserver...although it would be more secure to move the webserver to
wherever squid sits and give it the 12.12.12.12. ip address.

In a nutshell, everyone thinks your proxy is your webserver. If it goes
down
people will still try to reach it.
