US Patent 9769030 Page prefetching

A method for optimizing resource prefetch criteria may include identifying a prefetch criteria on a first resource. The prefetch criteria may be associated with a likelihood that a second resource linked from the first resource may be requested. The prefetch criteria may be modified to a modified prefetch criteria different from the prefetch criteria. A modified likelihood that the second resource may be requested may be tracked based on the modified prefetch criteria. The prefetch criteria may be replaced with the modified prefetch criteria when the modified result is greater than the result.
