F5 Networks Inc., today announced that it has been awarded a patent for its Cookie Persistence technology. F5’s patented Cookie Persistence technology uses an HTTP cookie stored on the customer’s computer to allow the customer to reconnect to the same server previously visited at a Web site. This is important, for example, where a customer adds items to a shopping cart at a Web site, then leaves the site before completing the transaction. When the customer returns, Cookie Persistence allows a traffic management device to direct the customer to the server that has stored the customer’s shopping cart information, allowing the customer to complete the transaction. Without Cookie Persistence, the traffic management device could direct the customer’s request to a different server, which may not know about the customer and his shopping cart status. F5 has already filed patent infringement lawsuits against a number of companies.
