Coloc question

Hi,

If Coloc is enabled on the client side, it will detect whether the server is
local or not. Some questions:

1. What if I do not use Coloc feature and still make my client and server
run in same JVM. Will it work?
2. Is the only role of coloc is to detect the location of server? (whether
local or remote) Which interceptor actually does that IN or OUT?

Thanks.

Raj

Yes. It would just use whatever protocol is normally used.   However, you do 
have to be slightly careful of potential deadlocks.    For example, if the 
server HTTP pool is set for 25 threads/connections, and all 25, at the same 
time, try to use a client that calls back into the server via http, they could 
fail or timeout as the server wouldn't have any more threads left to process 
those requests.

It's the ColocOutInterceptor that would be on the Clients out chain.
