1. A method of retrieving web-site based information using a spider engine at a target bandwidth, comprising the steps of:

  • (1) receiving a target bandwidth, BT, at which rate data is desired to be retrieved from a remote web-site to a local processor, wherein the data desired to be retrieved is allocated in storage at the remote web-site in a manner not known to the local processor;

    (2) calculating a wait time, TWAIT; and

    (3) delaying data retrieval from the remote web-site to the local processor by said calculated wait time to retrieve at the target bandwidth, BT, wherein an instance of a timing module is created by the spider engine to calculate said wait time; and

    wherein data retrieved to the local processor from the remote web-site passes through the Internet.
