HTTP compression

HTTP compression is a capability that can be built into web servers and web clients to improve transfer speed and bandwidth utilization. b HTTP data is compressed before it is sent from the server: compliant browsers will announce what methods are supported to the server before downloading the correct format; browsers that do not support compliant compression method will download uncompressed data. The most common compression schemes include gzip and Deflate, however a full list of available schemes is maintained by the IANA. Additionally, third parties develop new methods and include them in their products, for example the Google Shared Dictionary Compression for HTTP (SDCH) scheme implemented in the Google Chrome browser and used on Google servers.
