Hi All,
so the 3rd party will set up a webservice for me! That's a
good news.
This means my scenario is now as this:
I will set up a .net webservice which will expose one
method.
My client will be calling this method, and I need to pass it
on to the 3rd
party web service and wait for the response, then pass it on
to my client.
I will be connected to 3rd party via VPN.
What security considerations should I have? And what should
I demend on my
client? I hope the client will have to have a VPN to me as
well, but if it
doesn't what would you recommend?
I suppose my client should be calling my method
asynchornously, and as well
I should be calling my 3rd party asynchronously?
Thank you for all your help on this!
Mike
