Abstract

A computer system and method uses a client computer providing a browser and a decompression module, at least one compression proxy comprising a CPU, a memory device, device for sending requests, device for receiving requests, device for sending data, device for receiving data, and data compression device, and a server, the client computer, compression proxy and server, is interconnected through a wide area network, with the compression proxy further interconnected to a user database. The method comprises the steps of receiving requests for data from a client computer, checking authorization of the requests for data, rejecting unauthorized requests for data, sending authorized requests for data to a server, receiving data from the server, checking if the data are suitable for compression, sending unsuitable data to the client computer, compressing data suitable for compression, sending compressed data to the client computer.

Claims

1. A computer system apparatus comprising:

a client computer providing a browser and a decompression module;

at least one compression proxy comprising a CPU, a memory means, means for sending requests, means for receiving requests, means for sending data, means for receiving data, and data compression means; and

a server;

the client computer, compression proxy and server, interconnected through a wide area network;

the compression proxy further interconnected to a user database.

2. The apparatus of claim 1 wherein the client computer further comprises a software module providing a transformation means.

3. The apparatus of claim 1 further comprising a caching proxy.

4. A computer system method comprising the steps of:

receiving requests for data from a client computer;

checking authorization of the requests for data;

rejecting unauthorized requests for data;

sending authorized requests for data to a server;

receiving data from the server;

checking if the data are suitable for compression;

sending unsuitable data to the client computer;

compressing data suitable for compression;

sending compressed data to the client computer.

5. The method according to claim 4 further comprising the step of changing the requests for data according to an HTTP requirement.

6. The method according to claim 4 further comprising the step of providing a credentials field and a user field in each of a plurality of database records.

7. The method according to claim 6 further comprising the step of performing the operations of adding a user, deleting a user, and looking up credentials, on the database records.

8. The method according to claim 6 further comprising the step of setting client credentials in a proxy-authorization field of a HTTP request.

9. The method of claim 4 further comprising the step of using a lossless compression method.

10. The method of claim 4 further comprising the step of increasing a maximum number of connections allowed between the client computer and the proxy computer.

11. The method of claim 4 further comprising the step of using a file extension of a requested URL in determining a destination of a data request.

12. The method of claim 4 further comprising the step of connecting the client computer through one of a dial up network and a wireless network.

13. A computer system method comprising the steps of:

searching a credentials lookup table for a client computer;

authorizing the client computer if credentials of the client computer are found in the credentials lookup table;

searching a database for the client computer if the client computer is not found in the credentials lookup table;

authorizing the client computer if the client computer is found in the database and the client computer has approved credentials;

rejecting the client computer if the client computer is not found in the lookup table nor in the database;

storing an IP address of the client computer if the client computer is authorized;

allowing all requests from the stored IP address for a selected period of time; and

renewing credentials after the selected period of time has elapsed.
