An emerging type of dynamic caching will potentially save IT managers time and money, according to analysts. FineGround Networks, a new company, will be the first to offer this type of dynamic caching. Its Condenser software sits at the content site between the web server and the firewall, and speeds delivery by identifying and transmitting only the changed elements in a page. Dynamic caching limits updates to portions of a page that actually change. Companies in this area have focused on that mission and paid little attention to the delivery of that data, said Nat Kausik, CEO and president of FineGround.

As information changes, it sends out only the changes to the end user. Another dynamic-caching vendor, SpiderCache, said most products focus on reducing the amount of information the application server has to create. SpiderCache next week plans to introduce products that address delivery issues, said CEO and president Greg Parker. Condenser has intelligence that enables it to self-adjust to network conditions, said HTRC Group analyst Greg Howard. One Condenser beta tester, an IT director from a leading online brokerage, on occasion has reduced by 90 percent the number of bytes that need to be downloaded by users during subsequent visits to the same page, leading to faster overall page delivery.
