Exploring a New Product??”Proxy Server
In 1996, the Internet browser wars between the Netscape Navigator product and
Microsoft??™s Internet Explorer were in full swing, and Microsoft was constantly looking for
ways to improve the capabilities of Internet Explorer. Netscape had begun to sell a web
proxy product, which optimized Internet web browsing by caching the images and text
from web pages to local servers, enabling clients to access them quickly. At this time,

products to optimize these connections.

of the product were significantly less than those of Netscape or other proxy products
available at this time, however, and industry support for the product was lacking.
Following closely on the release of version 1.0 was version 2.
