All HTTP (Port 80, i.e., World Wide Web) traffic is directed to the optimization process. The direction of traffic to the optimization process is established when the user starts an HTTP data session before any requests for content from a specific web site have been made. Accordingly, content files are not selected for optimization based on the nature of the web content itself or the source or provider of the web content file. All web content files delivered over Port 80, regardless of source, are directed to the optimization process. The system thus captures all Verizon Wireless branded web content delivered from its web servers, and treats such content in the same way as content of the same type requested from non-Verizon Wireless sites on the Internet.
Content files made available on the World Wide Web come in a variety of types (web pages, text, image, video) and formats. The process incorporates several optimization techniques that depend upon the specific type of content file. Specifically, text files are compressed without any loss of information (“lossless”) and cached for subsequent end user requests. Image files (PNG, JPEG, GIF formats, for example) are streamlined to remove colors or other data bits that would not be visible to the human eye, or to end users on a mobile device with limited display resolutions, thereby decreasing the size of the file, and also cached. The output image file reflects “lossy” optimization because some data bits from the original file are lost in the optimization process.
