Resend from origin, or compress on edgeCotendo also offers the possibility to deactivate Gzip on the origin and have Cotendo do the Gzipping on their servers (compression-on-the-fly), for an even faster delivery to end users and less load on the origin. And, Cotendo supports exclude lists. If a specific user-agent requests a compressed object, the Cotendo server can decide to send it uncompressed due to known compliancy issues that the user-agent might have.
