WebServices chaining

[Borut Bolcina]

Hello.

I have just finished reading theory at some web sites concerning Web 
Services talking to each other. Although I got some insight, it would 
be great if someone has experience or even some guidelines to kick 
start me. Lots of fog everywhere.

I have successfully implemented clients and server, but I must 
implement a "mediator" - something that acts as server and client. This 
mediator does some processing and forwards the request to another web 
service. When the response is generated the mediator gets it, does some 
further processing and returns the response to the originator of the 
request - the original client.

I guess this is not too hard to do, is it? The requests will be coming 
in "hopefully" at short intervals, but the response time varies from 
seconds to a minute. Obviously the responses won't be served on a FIFO 
basis. Will I have to manually "bind" the right requests with the right 
responses and what is there for me to identify them uniquely OR is 
there a mechanism that does this for me - some kind of dispatcher?

I will appreciate some guidance very much.

I wish you a nice and successful day!
