MaxCDN has introduced multiple levels of GZIP compression. This feature is particularly useful for users of download managers and those who use a multi-CDN setup and need to keep the file size of their assets consistent.
The feature has been available for a while through support but now the webinterface has been updated to allow easy modification without the need for help from the people of MaxCDN support. MaxCDN has also updated its API and SDKs to include this functionality. More information on the API can be found here
