A method and system for monitoring the internet is defined. The system includes a sensor and a controller. The invention also provides an optical device comprising a substrate; and first and second optical components formed on the substrate, wherein the first optical component has two modes, each mode producing a different optical response to light incident thereupon, and wherein the second optical component absorbs light and is formed on the substrate before the first optical component is formed. Trend information is usable to enhance a response of an automated search agent to a subsequently received query. Data elements for a data line transfer can be driven, for example, using a quad pumped signaling mode in which four data elements are driven during one bus clock cycle. That is, an HTTP request can be dispatched to a designated server implemented method without having to include additional dispatch metadata within the HTTP request.
