Abstract
Abstract A method and system for invoking by a client computer system of a function of an object of an object class provided by a server computer system. The client sends a request to a server that comprises a Universal Resource Locator (“URL”) that identifies a script, an object class, and a function of the object class to invoke. In response to receiving the request, the server starts the script and transfers control to the script. The script instantiates an object of the object class identified in the URL of the received request and invokes the function identified in the URL of the received request. The invoked function performs the behavior of the function, creates a response to be sent to the client, and sends the response to the client. The response contains state information describing a state of the object after the behavior of the function is performed. When the client subsequently sends a request to invoke a function of the object class, the state information is included in the request so that the function can perform its behavior based on the state information.

Claims Analysis
Total Claims: 47
Claim 1
Independent Claim
151 words
A method in a computer system for processing of Hypertext Transfer Protocol (“HTTP”) requests before processing by an HTTP server, the method comprising: providing an HTTP template having command lines, each command line specifying a command to perform on an HTTP request; for each command line in the HTTP template, performing the command of the command line on the HTTP request to generate a shadow HTTP request; for each line in the shadow HTTP request, determining whether the line contains a substitute parameter or a function parameter; when the line contains a substitute parameter, replacing the substitute parameter in the shadow HTTP request with a value defined for that substitute parameter; and when the line contains a function parameter, invoking a function indicated by the function parameter so that the invoked function can modify the shadow HTTP request; whereby a final HTTP request is generated for processing by the HTTP server.
