I am not sure if this is the right platform to ask this question. But still asking in a hope to get some good pointers.
In a typical B2B setup, there is a Proxy installation done in DMZ, for both out-bound and in-bound calls.
As per my understanding:
webMethods Enterprise Gateway, in DMZ, is being used only for in-bound calls and not for out-bound.
For out-bound calls, it is generally an organization wide proxy being used. Now for B2B transactions, some organizations use other application specific proxies (Like: Bluecoat, Layer 7 etc…).
My question is regarding the out-bound calls, why do we need an additional proxy for out-bound calls. And what role do they play in Secure tranactions (SSL).
Any study material to understand this whole set-up would be a great help here.
Thanks in advance for your reply.
