Abstract

A system obtains a script containing at least one transaction to be performed with the web site, the at least one transaction defining a sequence of page requests identifying at least one web page to obtain from the web site. The system executes the script to perform the at least one transaction, performance of the at least one transaction including retrieving the sequence of the at least one web page. The system detects a capture event associated with the at least one web page, and in response to the capture event, captures content of the at least one web page. The system packages the content of the at least one web page into a container capable of being rendered, such that the container provides a plurality of components associated with the at least one captured web page, and delivers the container to a repository.
