In response to a request to download a product, a vendor sends a payload containing an installer, a download application (AP) containing the location of the requested product at a server, and a simplified version of the download application (AC). When the user executes the payload it launches the installer which checks whether or not a copy of AC exists on the user's computer. Should the user's browser support Active X Controls, the user is served a slight variation of the invention avoids this one-time manual execution of the payload. If AC is not found by the installer, a copy of AC is stored onto the computer. The installer then launches the AP application. The AP download application is of such a design that after its execution, no other steps are required by the user to view its graphical user interface (GUI). The user then may instruct AP, via its GUI, to initiate the download of the product, or the initiation of the download may be performed automatically. Subsequently, when such a user requests to download a product from a vendor that has installed the present invention, again the vendor sends the payload. The user's browser delegates the downloading and execution of the payload to AC, which has previously been stored on the user's computer. Once executed, the payload directly yields the GUI of AP without requiring any steps by the user as before, who may then instruct AP to initiate the download, or the initiation may be performed automatically. |
