A plurality of requests for a first content is received from the same browser. Each of the plurality of requests includes a previously generated value (PGV)/cookie. For each of the plurality of requests, a fast-hash is performed on the same PGV/cookie to generate an identifier (e.g., number). It is then determined whether to provide a second content instead of the first content based on whether the identifier is in the range associated with the at least one group of visitors. The determination may also be based on a URL filter, a browser type, operating system type, a time-range, or an argument-value pair. The first or second content is then provided.
