Running 2 Proxy servers

[julianf]

Hi,

We installed a 128K line to our ISP. The old 64K line is still active though. Our proxy 2.0 server now controls the 128K line though. In the past, we had a Proxy server with 2 network cards, one Internal and one external (live). i would like to make use of the 64K line for internet usage as well.

Do i have to install another Proxy server. (The 2 diginet lines going to ISP are both on seperate routers with differnt ip ranges as well).

Any info would be appreciated.

Regards,

Julian

There are few tricks to use both conenctions to the internet (both proxies).
First they should be on different machines. Then you have to implement a Round Robin DNS (assign to a name to machines):
myproxy IN A 192.168.0.1
myproxy IN A 192.168.0.2

myserver1 IN A 192.168.0.1
myserver2 IN A 192.168.0.2

The trick is that DNS will answer with a random address between the two that you have.
The latest versions of DNS servers will know how to manage this.

Of course this is not a load balancing solution. But it works. You can try to search on the internet about Round Robin DNS method.

About load balancing,... honestly I don't know any proxy that can do this. Just tricks like hierarhical caching,.. etc. But these it's about the way you can make them to communicate between them. Accesing them, will always be a problem, that until now I see that just Round Robin DNS can solve it.

Success! Gia Betiu
