Translations:Compression/3/en

It is possible, with HTTP, to compress individual pages served. Both the browser and the server must support it, and it is normally negotiated, (with uncompressed version available). This is on by default if PHP has zlib support enabled (no Apache mods are required). The negligible CPU time spent compressing on the server is dwarfed by things like loading the PHP scripts, and the bandwidth savings are considerable.
