Service To Compress and GZip

Has anyone comes across a service which you can send JavaScript and have it return it compressed and gzipped? Ideally I would like to serve up JavaScript using a single request which sends it to some service and sends it back compressed and gzipped. I’m not really worried about the additional time it will take the service to send back the JS since there will be caching involved as well. Something like tinySrc but for compressing and gzipping would be perfect.
