Hi Tyson, What's version of resin is this on?
thanks Alex > > Not sure this is a bug with GzipFilter or expected behavior, but found > something worth sharing and dropping in the forum record for others to find. > > We had a problem distributing content to a CDN and keeping it in cache there > because the CDN was requesting content with an "Accept-Encoding: gzip" > request header, which was causing our GzipFilter to slap a "Cache-Control: > private" response header via the http response object.
