Method and apparatus that enables a web-based client-server application to be used offline

A computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method for using a web-based client-server application offline, the method comprising:

• receiving a function call at an object within a browser which is executing on a client, wherein the function call is generated by the web-based client-server application and is directed to a communication layer on the client;
• determining an intended resource for the function call;
• determining if the function call should be redirected to an alternate resource;
• if so, redirecting the function call to the alternate resource;
• and
• if not, forwarding the function call to the intended resource.

An apparatus configured for using a web-based client-server application offline, comprising:

• a web browser;
• a receiving mechanism configured to receive a function call at an object within the browser executing on a client, wherein the function call is generated by the web-based client-server application and is directed to a communication layer on the client;
• a determination mechanism configured to determine an intended resource for the function call;
• wherein the determination mechanism is further configured to determine if the function call should be redirected to an alternate resource;
• a redirection mechanism configured to redirect the function call to the alternate resource if the function call should be redirected;
• and
• a forwarding mechanism configured to forward the function call to the intended resource if the function call should not be redirected.
