CSS 11000/11500 GSLB based on URI

[mchoo2005]

Hi,

Our customer is currently using CSS 11000 (to be upgraded to CSS 11500 in the next few weeks) to globally load balance their applications across two data centres (DCs).

They are planning to introduce 3 new apps that will require GSLB functionality across the two DCs. But, they want to refer to each app using the same domain name, but different URI. E.g.: foo.mycompany.com/AppA, foo.mycompany.com/AppB, and foo.mycompany.com/AppC.

All I know is that CSS can only offer GSLB functionality based on URLs (i.e. AppA.foo.mycompany.com, etc. etc.).

Question: Can CSS perform GSLB based on URI as requested by our customer? If so, how?

Thanks so much in advance for your help!

Cheers

GSLB or DNS is domain <-> ip.

When a client makes a dns request, nobody knows yet what url it will send.

You only get the url, when the client already knows the server ip address.

So, there is no way to achieve what your customer wants.

What can be done is configure gslb normally [as if there was a single app] and then if necessary under the content rule you can configure a redirect service to loadbalance the client request to another DC.

Gilles.

Thanks Giles. You have just confirmed my own understanding.
