Web Site Optimization - GZip compression
HTTP compression, otherwise known as content encoding, is a simple, effective way to save bandwidth and speed up your site. It improves the performance and highly decreases its loading time.
The mechansm is a publicly defined way to compress textual content transferred from web servers to browsers. HTTP compression uses public domain compression algorithms, like gzip and compress, to compress XHTML, JavaScript, CSS, and other text files at the server. This standards-based method of delivering compressed content is built into HTTP 1.1, and most modern browsers that support HTTP 1.1 support ZLIB inflation of deflated documents. In other words, they can decompress compressed files automatically.
