Check HTTP compression
HTTP compression is a capability that can be built into web servers and web clients to make better use of available bandwidth, and provide faster transmission speeds between both. 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 schemas include gzip and deflate.
This tool lets you know if the webpage is compressed or not and other compressing details like the compression method etc.

Your browser Support "x-gzip, gzip, deflate" http compression
Type of http compression
- UNIX "compress" program method
- despite its name the zlib compression (RFC 1950) should be used (in combination with the deflate compression (RFC 1951)) as described in the RFC 2616. The implementation in the real world however seems to vary between the zlib compression and the (raw) deflate compression. Due to this confusion, gzip has positioned itself as the more reliable default method.
- W3C Efficient XML Interchange
- GNU zip format (described in RFC 1952). This method is the most broadly supported as of March 2011.
- Google Shared Dictionary Compression for HTTP
- free and open source lossless data compression algorithm
- Microsoft Peer Content Caching and Retrieval (described in MS-PCCRPT)
