4.2. Web services transports

The transport of SOAP messages for web services nearly always takes place over http(s). Like mentioned before, the Internet is the preferred transportation network for web services and naturally http is used for transport. If using http, one can usually rely on a very good infrastructure, because http is commenly used in all other places – for the www services. Accordingly you have fewer problems with firewalls and such things: „http always works!“.
