Abstract

A system is shown that supplies web pages from servers (109 to 116, 301 to 305) to requesting clients (102 to 106) over the Internet (101). Each server is configured to supply web page data to requesting clients. A traffic manager (120) receives request data from browsing clients and selects one of the serving devices for serving web page data. A data manipulation station (125) manipulates request data or web page data. The traffic manager supplies a function call to the data manipulation station that includes request data or web page data using Internet protocol. The manipulation station manipulates the request data or the web page data to produce manipulated data and the manipulated date is returned to the traffic manager.

Claims

1. Apparatus for supplying web pages from servers to requesting clients over the Internet, comprising:

a plurality of servers, each configured to supply web page data to a plurality of requesting clients;

a traffic manager configured to receive request data from browsing clients and to select one of said serving devices for serving web page data to the requesting client; and

a data manipulation station configured to manipulate said request data or said web page data, wherein;

said traffic manager supplies a function call to said data manipulation station that includes request data or web page data using internet protocol;

said manipulation station manipulates said request data or web page is data to produce manipulated data; and

said manipulation station returns said manipulated data to the traffic manager.

2. The apparatus of claim 1, wherein said manipulation station is configured to manipulate request data, a manipulated request is returned to said traffic manager, said traffic manager selects a server based on said manipulated request, and web page data is returned to the requesting client from the selected server.

3. The apparatus of claim 2, wherein said manipulating station has access to a database and the nature of the manipulation is dependent upon stored data read from said database.

4. The apparatus of claim 3, wherein said database stores details of authorised users and said stored data confirms a requesting client is an authorised user.

5. The apparatus of claim 4, wherein said manipulated request identifies a request as authorised or not authorised.

6. The apparatus of claim 2, wherein the manipulating station requests additional data about the requesting client from the traffic manager.

7. The apparatus of claim 6, wherein the traffic manager tracks repeated requests for additional data and after a predetermined number of repeated requests (or repeats within a specified period) the traffic manager anticipates the request for additional data and sends said additional data without said additional data being requested.

8. The apparatus of claim 1, wherein said manipulation station is configured to manipulate web page data, the traffic manager selects a server, the web page data is supplied from the selected server to the traffic manager, the traffic manager makes a call to the manipulation station with the web page data, the manipulation station manipulates the web page data, the manipulated web page data is returned to the traffic manager, and the traffic manager serves the manipulated web page data to the requesting client.

9. The apparatus of claim 8, wherein said manipulation station is configured to modify or delete specified textural matter.

10. The apparatus of claim 8, wherein said manipulation station is configured to modify page bandwidth.

11. A method of performing a traffic management function to facilitate the supply of web pages from servers to requesting clients over the Internet, comprising the step of:

receiving request data from a browsing client to supply web page data to said browsing client from a server;

comprising the steps of;

supplying a function call using internet protocol to a manipulating station configured to manipulate said request data;

receiving manipulated request data from said manipulating station using internet protocol in response to said function call;

using said manipulated request data to address a server,

receiving web page data from said server in response to said manipulated request data;

and serving said received web page data to said browsing client.

12. The method of claim 11, wherein said manipulating station assesses whether a user of said browsing client is an authorised user by accessing a database.

13. The method of claim 11, wherein a request for additional information about a user or a browser is received from the manipulation station.

14. The method of claim 13, wherein request type frequencies are monitored to anticipate requests from the manipulation station.

15. A method of performing a traffic management function to facilitate the supply of web pages from servers to requesting clients over the Internet, comprising the steps of:

receiving request data from a browsing client to supply web page data to said browsing client from a server;

requesting web page data from a selected server in response to said request data;

supplying a function call using internet protocol to a manipulating station configured to manipulate said web page data;

receiving manipulated web page data from said manipulating station using internet protocol in response to said function call; and

serving said manipulated web page data to said browsing client.

16. The method of claim 15, wherein said manipulating station assess whether a user of said browsing client is an authorised user by accessing a database.

17. The method of claim 15, wherein a request for additional information about a user or a browser is received from the manipulation station.

18. The method of claim 15, wherein request type frequencies are monitored to anticipate requests from the manipulation station.
