  • Compression =”on” Enable Gzip compression, default is off

  • Use compressionMinSize=”2048″ to compress files larger than 2KB, which consumes CPU performance. Use compressionMinSize only for resources larger than 2KB, which is officially recommended.

  • NoCompressionUserAgents =”gozilla, Traviata “, for both browsers, no compression is performed;

  • compressableMimeType=”text/html,text/xml,text/plain,text/css,text/javascript,text/json,application/x-javascript,applicat Ion/javascript, application/json “suggests that support HTML, XML, js, CSS, and json compressed file format
