Claim:
A method of redirecting a request for a web service in a data transmission network wherein, in response to a request forwarded by a host of a client server to a web service provider, the web service provider provides a Web Service Definition Language (WSDL) file based upon a message exchange protocol on a transport protocol; said method comprising: forwarding a first request from the client server to an address of said web service, determining the address of the web service is an old address by checking a list of outdated web services, wherein each web service in the list is associated with the old address and a new address; responding to the client server from a web service point associated with said old address by sending back a message with a header, wherein the header using said message exchange protocol contains a redirection to the new address associated with the requested web service, checking, using a checker on the client server, for the redirection in the header of the message, wherein the redirection includes a redirection command that is included in a specification of the message exchange protocol; and forwarding a second request from the client server to the new address of the requested web service.
