Thorpe's example only works if Server B has a webserver running on it. That has not been stated. The first post stated that Server A has a web server running but says nothing of what's running on server B.
i_s_r_a_e_l, we need to know what services will be available on all the machines involved in this scenario. Does Server B have a web server running? If not, what does it have and what can it have?
