.NET Forum / ASP.NET / Web Services / August 2004RPC vs. Http
What are the differences between a http web service and a rpc web service ? Can I build an rpc based web service with VS.NET.2003 ? My understanding is that "Remoting" is more involved and requires setting up listeners. > What are the differences between a http web service and a rpc web service ? > > Can I build an rpc based web service with VS.NET.2003 ? You are right. Remoting does require setting up listener programs on ports specified by the developer. RPC is of most use internally, because remoting does not work for machines behind NATed firewalls. RPC also uses a binary protocol which is much lighter and faster than HTTP protocol. This introduces another problem if you are thinking of using Remoting for general use from a web page. Most firewalls block anything that is not FTP or HTTP traffic - that includes RPC protocols. Although Remoting excited me when I first heard of it, I quickly lost interest when I realized the extremely limited usefulness of the technology due to NATs and firewalls.

But you can use SOAP formatters and specify the port to listen to on the server side with Remoting so where is the problem? You can even use an HTTP channel so this should work quite well (in theory) through NAT and firewalls. http://groups.google.com/groups?hl=en&lr=lang_en&ie=UTF-8&safe=off&edition=us&th readm=v2jtr7qb695fee%40corp.supernews.com&rnum=1&prev=/groups%3Fnum%3D100%26hl%3 Den%26lr%3Dlang_en%26ie%3DUTF-8%26safe%3Doff%26edition%3Dus%26q%3Dremoting%2B%25 22jim%2Bhubbard%2522 > > Although Remoting excited me when I first heard of it, I quickly lost > > interest when I realized the extremely limited usefulness of the [quoted text clipped - 4 lines] > channel so this should work quite well (in theory) through NAT and > firewalls.
