mod_deflate is an optional module for the Apache HTTP Server, Apache v2 only. Based on Deflate lossless data compression algorithm that uses a combination of the LZ77 algorithm and Huffman coding. This module provides the DEFLATE output filter that allows output from Apache HTTP server to be compressed before being sent to the client over the network. It also provides a filter for ''decompressing'' (''inflating'', ''uncompressing'') a gzip compressed ''response body''.〔(mod_deflate also provides a filter for decompressing a gzip compressed response body )〕 The mod_deflate module does not have a lower bound for file size, so it attempts to compress files that are too small to benefit from compression. This results in files smaller than approximately 120 bytes becoming larger when processed by mod_deflate. ==Compatibility== You can check a server to see if it is sending out compressed data, and compression compatibility of your browser for example (here ). When textual content compressed using mod_gzip, it should maintain its MIME-type, according to their recommended media type: * HTML: text/html * XHTML: application/xhtml+xml * CSS: text/css * JavaScript: application/x-javascript 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mod deflate」の詳細全文を読む スポンサード リンク
