1. In a computing environment, a method of enabling design and testing of web pages locally at a local machine, wherein after being designed and tested at the local machine, the web pages will be deployed at a remote server remote from the local machine, and where the web pages include relative references to resources from the perspective of the remote server, wherein the relative references to resources are intended to be resolved by the remote server, the method comprising: accessing code at a local machine, the code defining a web page, wherein the code includes relative references to resources, the relative references being expressed from the perspective of a remote server remote from the local machine, such that the relative references are only natively resolvable by the remote server; and translating the relative references to local references which are references resolvable by the local machine such that the local machine can resolve the local references to the resources.
