Pros and Cons of Web Services Versioning Strategies

Question

Answer 1

Web services in our application are just a front-end to the business logic.

New version of web service appears due to business logic change. When new version of web service is introduced it is placed under new url. For instance:

ver1 /websvc
ver2 /websvc2

There is special code between web service layer and business layer. This layer handles differences in the web services versions and passes a call to the latest business layer.

It is the problem of the special facade code (between web service and business logic) to know web service version differences.
