Is it possible to connect to two different clusters?

Question

Hi,
I was wondering if it was possible to connect to two different clusters from the same process?
What I would like to do is to able to get some cache on the first cluster and others on a second cluster. The cache-config DTD doesn't seem to forbid the definitions of several remote-cache-scheme. So I should be able to map all "c1-*" caches to the first cluster and all "c1-*" caches to a second cluster...
Is it possible?

Thanks,
Yes I'm connection via extend.
Could you give me an example of such configuration? I've made a test from a C++ client with the following client config:

if I do a CacheFactory::getCache("c1-Test"), the log shows a connection to the 1st cluster
if I then do a CacheFactory::getCache("c2-Test"), the log shows a connection to the 1st cluster and not to the second cluster
What did I do wrong?
