Issue/Introduction

The following MIME types are served by the ProxySG uncompressed by design of the SGOS even if there is policy in place to force compression:

“application/pdf”
“application/futuresplash”
“application/gzip”
“application/x-gzip”
“application/x-shockwave-flash”
"application/x-compressed"
"application/x-zip-compressed"
"application/x-gzip-compressed"
"application/x-rtsp-tunnelled"
"application/zip"
"audio/*"
"video/*"
"image/gif"
"image/jpeg"
"image/pjpeg"
"image/png"

Certain MIME types may exist in this list for the following reasons:

  • There is already a compression algorithm in use by the application
  • There is little to no benefit in applying compression for the type of content
  • There is no efficient method for applying compression for the type of content


What is gained by disabling compression for these MIME types?

Disabling compression on the above content saves on CPU usage. This is ideal when there is no benefit (file size is not decreased) in applying compression to the content.
