Abstract
Features are disclosed for efficiently maintaining information regarding content navigation history and state of a browser application. The browser application can use a portion of a client device's non-persistent memory that has been assigned a direct byte-for-byte correlation with a file in persistent storage, such as a memory-mapped file. The browser application can access, store, and update information in the memory-mapped file in non-persistent memory without being responsible for ensuring that updates are also reflected in the file stored in persistent storage. The operating system of the client device can handle the tasks of writing to, and reading from, persistent storage.
