What are the components of pageVault?
pageVault consists of these components: • Filter Runs inside the web server’s address space, identifying potentially unique request/response pairs and writing them to disk. Because the filter does not have a global view of the web server (many web servers are at least multi-processing and often run across several machines at different locations), and only maintains a local and recent history of what responses have been sent, it will generate some “false positives”: request/response pairs which are not really unique. These false positives are identified in subsequent components. • Distributor Runs as a separate process, usually on the same machine as the web server, reading the temporary disk files of potentially unique responses generated by the filter. The distributor is able to immediately identify most of the false positives generated by the filter, removing them from further processing. The request URL and checksum of the remainder are sent to the archiver component, and if deemed
