A system and method for accelerated downloading of dynamic web pages. Initially, customized script library functions are downloaded from the server to the client browser as part of the page frameset. A page request from a user is received by the client browser and transmitted to the server. In turn, page data is fetched by the server from remote data sources and formatted to include library code for invoking associated library functions written in a script programming language, e.g., JavaScript. The formatted data pages is transmitted from the server to the client browser which calls the library functions that were previously downloaded to the client browser in response to the library code in the data pages. The appropriate library functions are invoked from the client browser to generate Hyper-Text Markup Language code that is written to a target frame. Finally, the Hyper-Text Markup Language code written to the target frame is rendered. The downloaded JavaScript library functions are therefore downloaded to the client side only once but accessed multiple times thereby increasing efficiency of downloading and reducing bandwidth. Faster page draw is achieved because of the limited amount of information or data that is repeatedly transferred to the client browser from the server.
