715191 - HTTP cache: compress more compressible files

Status: RESOLVED WONTFIX

(Core :: Networking: Cache, enhancement)

Description

[dagyju-199]

Currently we compress, in the cache, few types of files :
TEXT_HTML, TEXT_PLAIN, TEXT_CSS, TEXT_JAVASCRIPT, TEXT_ECMASCRIPT, TEXT_XML, APPLICATION_JAVASCRIPT, APPLICATION_ECMASCRIPT, APPLICATION_XJAVASCRIPT, APPLICATION_XHTML_XML

We can add many others types of files :
APPLICATION_JSON, APPLICATION_PDF, APPLICATION_RDF, APPLICATION_POSTSCRIPT,  APPLICATION_XHTML_XML, APPLICATION_XSLT_XML, APPLICATION_MATHML_XML, APPLICATION_RDF_XML, AUDIO_WAV, IMAGE_GIF, IMAGE_BMP, IMAGE_SVG_XML, TEXT_VCARD, IMAGE_XBM, ENCODING_BINARY, ENCODING_BASE64

... and IMAGE_ICO because it's a container for BMP (bitmap).
