Abstract
The present invention relates to systems and methods for content resizing and caching in multi-process browser architecture. An embodiment includes initiating a rendering engine process and a browser process, receiving a request to resize content, providing the request to the rendering engine process, waiting to allow the rendering engine process to render an updated bitmap associated with the content and displaying the updated bitmap synchronously if the updated bitmap is produced during the waiting step. Another embodiment includes, receiving an input associated with the status of a tab, determining if the tab is a background tab or a foreground tab based on the receiving step, checking a cache for a bitmap of content associated with the tab if the tab has changed status to a foreground tab; and displaying the contents of the cache in the tab if the cache includes the bitmap of content previously associated with the tab.
