Abstract: Methods and products for providing content to a user window on a client computer without the need for reloading or refreshing a whole web page. The content is sent to a synchronous window invisible to the user on the client computer in a format acceptable to the sync window. A user application can then retrieve the content from the sync window and present it to the user without the need to load the entire page. The transfer of content can be made even more efficient by sending the content in the form of browser script and without the need for vendor, program or application specific formats or converters.
