TOKEN BASED SOURCE FILE COMPRESSION/DECOMPRESSION AND ITS APPLICATION

摘要

A source file (110) is transformed into a tokenized form (112) with at least language elements present in the source file (110) in an original form being substituted with corresponding tokens to reduce transmission bandwidth required to provide the source file (152) to another computer system (140). In one embodiment, operands present in the source file (110) in the original form are also substituted with corresponding tokens, and entries mapping the operand substituting tokens to the operands are maintained in a symbol table. The symbol table is also provided to the other computer system (140). In one embodiment, the computer system is a web server (100), and the source file (110) is a web page. The other computer system is a client computer system (140) requesting the web page from the web server. The requested web page is provided by the web server (100) to the client computer system (140) in the tokenized form, and the client computer system (140) is equipped with a browser having been enhanced with the ability to restore the provided web page to its original form.
