One embodiment includes observing, with a web browser plug-in operating on a computer, at least a portion of a first web page transaction in a web browser operating on the computer. A web browser module may be used to identify transaction information from the observing of the at least a portion of the first web page transaction. The browser may communicates transaction information to a prefetching system in a communication separate from the first web page transaction; and the transaction information may be used to perform a prefetch operation. ## Claims ### Claim 1 A method comprising: receiving, by a browsing assistance system, a message comprising feedback information from a first client computer, the feedback
