(wrong string) : Handler problems

Do you want the Handler to intercept the
request/response on the client machine/container, the
request/response on the server machine/container, or
both?

If its the client or both, you need code similair to
what you are doing.

If its the server/both, you need a configuartion file
that the web service itself uses during configuration.
In this case, you would _not_ call HandlerRegistry,
because its encapsulated from the client.

Keep in mind there are reasons to have a client/both
architecture, such as to digitally sign/encrypt the
data the client is sending to the web service, or log
all client traffic, etc.
