A system, method, and computer program product verifies web page containers of software gadgets. A request for a software gadget is received by a gadget server from a web browser at a client. The request includes a container web page parameter that identifies a web page. The gadget server determines whether the identified web page is an acceptable web page for containing the requested software gadget. If it is determined to be acceptable, the requested software gadget is prepared by inserting container verification code into the gadget. When the prepared software gadget is provided to the client, the container verification code executes and ensures that the requested software gadget is contained within the identified web page. The container verification code may include code for setting a container web page of the prepared software gadget to be the identified web page and for preventing unnecessary page reloads.
