Subject: Added SVG to compressible mime types
X-Git-Tag: v4.4.0b1~56
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4cd47d666c9665c08b0ef1f8e12c42c871360d8c;p=thirdparty%2Ftornado.git

Added SVG to compressible mime types

This adds the mime type `image/svg+xml` to the whitelist of compressible mime types for the tornado.web.GZipContentEncoding class.

SVG images are served with the mime type `image/svg+xml`, but are not compressed by the GZipContentEncoding transform. My first thought was to add all mime types ending with `+xml`, but that might need a bit more research.
