Embodiment Construction

[0026] According to FIG. 1 , a server 1 and a client 2 are connected to each other via a transmission line 3 . As shown schematically in Figure 1, the transmission line 3 may be a LAN 3', or a point-to-point connection 3", such as a modem connection 3". The server 1 is preferably a Web (World Wide Web) server for the Internet.

[0027] The server 1 and the client 2 each have a main unit 4, 5. The master unit 4, 5 processes a computer program product 6, 7 with which the server 1 and the client 2 are programmed. The computer program product 6, 7 preferably comprises an Internet browser functionality, such as Internet Explorer or Netscape.

[0028] When processing the computer program product 6,7, the main unit 4,5 accesses the memory 8,9. In addition, server 1 and client 2 also communicate with each other. The server 1 is in interactive communication with an operator 12 at any time, eg for configuration or monitoring purposes, via an input device 10 and an output device 11 ....

Abstract

A transmission request for a compressible datafile is transmitted to a server from a client. The server transmits the compressible datafile or a corresponding, compressed compact datafile to the client dependent on whether the client also provided it with a compress command. The client receives the transmitted datafile and checks which of the two datafiles has been transmitted to it. When the compact datafile has been transmitted, then the client automatically decompresses it.

Description

technical field [0001] The present invention relates to a transmission method of compressible data, especially text data, such as html (hypertext markup language) data transmission method, wherein, the data is transmitted from the server to the client through the transmission line. Background technique [0002] Such transfer methods are generally known. Typically, a client sends a transfer request to a server. The server then transmits the compressible data to the client. When the compressible data is large, the transmission time will be very long. This is especially true if the transmission line is an ISDN or modem connection. Because the transmission bandwidth of this connection is relatively small. [0003] on internet pages http: / / www.w3.org / Protocols / HTTP / Performance / Compression / LAN.html The html data to be compressed is announced in and-PPP.html, and the compressed data is transmitted to the client by the server. Then decompress on the client side. [0004] H...
