Web services and Proxy

[Raymond Chiu]

Dear all,

Is the following correct?
(1) web services can be accessed by outsider or in the intranet
applications.
(2) asynchronous web services, like proxy on allocating resources?

What is the similarity and difference between asynchronous web services and
proxy server? It may be difficult to express my ideas as I find that there
is relation between asynchronous web services and proxy. But can
asynchronous web services achieve the function without using proxy? or What
is the purpose of using asynchronous web services with proxy?

Thanks,
