Scalability Issues of 'Cascading Request'
another question regarding intermediaries:
I am thinking about a system where requests running through intermediaries
might trigger them to issue multiple requests themselves (e.g. to harvest
information from multiple information services and send the combination
of all responses back to the client) and I am a bit frightened of the
traffic that such 'cascading requests' might cause.
Does anyone know if there has been reserach on this or similar topics,
especially regarding REST of course.
(The responses from the information services would all be cachable but their
diversity is rather unpredictable).
Any pointers to books, papers etc. where I could start researching would
really, really help. Thanks in advance.
 For example consider an intermediary that sends out a bunch of requests
per URI that it finds in RDF documents running through it, leading to maybe
hundreds or thousands of requests triggered by a single one through the
intermediary. Oh, and of course the intermediary is likely to send its own
requests through intermediaries of the same kind...
