MULTIPLE PARALLEL USER EXPERIENCES PROVIDED BY A SINGLE SET OF INTERNET HOSTING MACHINES

摘要

This disclosure describes techniques of using a hosting device to provide multiple versions of a single web application. As described in detail below, the hosting device stores resources associated with different versions of the web application in different subdirectories. When the hosting device receives a request associated with the web application, the hosting device automatically identifies one of the versions of the web application as an applicable version of the web application. The hosting device rewrites a pathname in the request to include a subdirectory name of the subdirectory that stores the applicable version of the web application. The hosting device then dereferences the resource identified by the rewritten pathname. In this way, the hosting device uses the resources of the applicable version of the web application to process the request.
