gzip support for Amazon Web Services CloudFront. This would have saved me a bunch of work a few weeks ago. CloudFront can now be pointed at your own web server rather than S3, and you can ask it to forward on the Accept-Encoding header and cache multiple content versions based on the result. # 12th November 2010, 5:33 am

Velocity: Forcing Gzip Compression. Almost every browser supports gzip these days, but 15% of web requests have had their Accept-Encoding header stripped or mangled, generally due to poorly implemented proxies or anti-virus software. Steve Souders passes on a trick used by Google Search, where an iframe is used to test the browser’s gzip support and set a cookie to force gzipping of future pages. # 30th September 2010, 5:45 pm

PNGStore—Embedding compressed CSS & JavaScript in PNGs. Cal did some further analysis on the CSS/JS to PNG compression trick (including producing some interesting images of jQuery compressed using different image packing techniques) and found it to be slightly less effective than regular GZipping. # 23rd August 2010, 9:47 am
