An approach is provided in which an information handling system begins by storing a first URL and a corresponding first web page dataset. The information handling system then receives a request to store a second URL and a corresponding second web page dataset. The information handling system determines that the second URL corresponds to the first URL and, as such, the information handling system creates a diff web page dataset based on a difference between the first web page dataset and the second web page dataset. In turn, the information handling system stores the second URL and the diff web page dataset.
