-Based Benefits"> Browser-Based Benefits condenser 3.0 relies on the end users browser to provide much of its pep. Specifically, this means support for HTTP 1.1, which is found in the vast majority of browsers, including most versions of Internet Explorer and Netscape. Browsers without this support can still work with an origin server that is using Condenser 3.0; they just wont get any of the benefits.The process works like this: A user requests a page from the origin server. Condenser 3.0 notes the request and issues a cookie to the user and creates a base page, which is a copy of the result generated by the server. A subsequent request for the same page by the same user or a different user who is known to Condenser 3.0 still generates a request to the origin server for the content. Condenser 3.0 compares the new content with the stored base page and then creates a delta file containing the changes. This page is compressed and sent to the user where the new content is used. In tests, the process worked smoothly and with no intervention required on our part.
We didnt have to make any change to HTML code to get Condenser 3.0 to work on the test system. Instead, Condenser 3.0 used its FlashForward technology and added tags and expiration dates to our objects (such as images) to reduce needless communication with the server. It goes without saying that this also expedited the use of cached objects on the browser. Furthermore, Condenser 3.0 also "condensed" pages to only the changes since the last request to reduce bandwidth consumption.
