Aixs support intermediaries

[susae lee <su...@yahoo.com>]

For the applications i worked on, it's only client / server - request / response, one - one communication. But when i read SOAP specification, it may have many intermediaries between the web service client and server
   
  Here is my question -
   
  1 -- Does Aixs support intermediaries and what is intermediaries used for?
   
  2 -- Does use of intermediaries happen often in the real world industry?
   
  3 -- What are example of intermediaries and use of it?
   
  4 -- Are those intermediaries just another SOAP engine (e.g. axis) sit on aother Computer / Host? 
   
  5 -- i also heard intermediaries modify the SOAP request / response too why they need to do so?
   
  6 -- i saw alot web service at www.xmethods.net they are all one - one --> request / response, did all the web services there ever use intermediaries? am i sending request to intermediaries or Ultimate soap receiver? Usually it will have 1 request, and then response XML when i click on "Try It" there.
