Abstract: A system and method for facilitating annotation of a digital document between first and second computing devices is provided. The system comprises a database/server that receives an original digital document from the first computing device and communicates a shared digital document to the second computing device. The second computing device receives and displays the shared digital document for annotation. The annotation produces an annotated digital document which includes annotated document data overlaying the original document without modification to the original document data. The original digital document may be edited at only the first computing device.

Abstract: Viewing of web pages is improved by prioritizing image rendering based on positioning of images within a web page. For example, for images that are likely to be initially viewable upon presentation of the web page (i.e., prior to scrolling), compressed proxy versions are made available so that the images can be transferred and rendered more quickly. These compressed proxy images are later replaced with better quality renderings of the same images. Fetching of images that are not initially visible can be deferred until after other, more important page resources are loaded. Prioritization of page loading in this manner helps to ensure that the page becomes operational earlier, resulting in improved perceived speed and responsiveness, and greater ease of navigation.

Abstract: A method and system for creating, distributing, and managing of shared compression dictionaries. The system comprises a compressor configured to generate at least one shared compression dictionary based on a context of data streams flow between a client web browser and an origin server; an origin accelerator communicatively connected to the origin server and configured to encode an encountered data stream to a compressed form based on the least one shared compression dictionary; and an edge accelerator communicatively connected to the client web browser and configured to decode the compressed form of the data stream to an uncompressed form using the least one shared compression dictionary.

Abstract: According to various embodiments of the present invention, acceleration can be used in connection with edge caching. Edge Side Landing Pages (ESL pages) are cached upstream on a Content Delivery Network (CDN), so as to reduce or eliminate round trips to the origin, thereby improving efficiency and reducing latency. ESL pages optimize performance for first time and repeat visitors for pages flagged to be cached upstream on the CDN. This allows pages cached on the CDN to be accelerated in addition to being cached. At the same time the system still efficiently serves requests to the origin for pages that are not cached on the CDN.
