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.
Claims28
A transmission method for a compressible datafile, comprising the steps of:
- establishing a transmission link between a server and a client;
- transmitting a request for a compressible datafile via said transmission link from said client to said server;
- at said server, checking whether a compress command was transmitted with said transmission request;
- and
- if said compress command has been transmitted, automatically transmitting a compact datafile, corresponding to said compressible datafile and being compressed relative to said compressible datafile, from said server to said client via said transmission link, and otherwise transmitting said compressible datafile to said client from said server via said transmission link.
A computer program product loadable into a server for causing said server to establish a transmission link with a client, receive a request for a compressible datafile via said transmission link from said client, check whether a compress command was transmitted with said transmission request, and if said compress command has been transmitted, to automatically transmit a compact datafile, corresponding to said compressible datafile and being compressed relative to said compressible datafile, to said client via said transmission link, and otherwise to transmit said compressible datafile to said client via said transmission link.
A server comprising a main computer unit programmed to establish a transmission link between a server and a client, receive a request for a compressible datafile via said transmission link from said client to said server, check whether a compress command was transmitted with said transmission request, and if said compress command has been transmitted, automatically transmitting a compact datafile, corresponding to said compressible datafile and being compressed relative to said compressible datafile, to said client via said transmission link, and otherwise to transmit said compressible datafile to said client via said transmission link.
A transmission method for a compressible datafile comprising:
- establishing a transmission link between a server and a client;
- transmitting a compress command from said client to said server via said transmission link associated with a request for a compressible datafile;
- in response to said request, receiving a datafile via said transmission link at said client transmitted from said server;
- at said client, automatically checking whether said datafile received at said client is said compressible datafile, or a compact datafile corresponding to said compressible datafile and being compressed relative to said compressible datafile;
- and
- if said datafile received at said client is said compact datafile, automatically decompressing said compact datafile at said client.
A computer program loadable into a client for causing client to establish a transmission link with a server transmit a compress command to said server via said transmission link associated with a request for a compressible datafile, in response to said request, to receive a datafile via said transmission link transmitted from said server, to automatically check whether said datafile received at said client is said compressible datafile, or a compact datafile corresponding to said compressible datafile and being compressed relative to said compressible datafile, and if said datafile received at said client is said compact datafile, to automatically decompress said compact datafile at said client.
A client comprising a main computer unit programmed to establish a transmission link with a server, transmit a compress command to said server via said transmission link associated with a request for a compressible datafile, in response to said request, receive a datafile via said transmission link transmitted from said server automatically check whether said datafile received at said client is said compressible datafile, or a compact datafile corresponding to said compressible datafile and being compressed relative to said compressible datafile, and if said datafile received at said client is said compact datafile, to automatically decompress said compact datafile at said client.
