Know It Or Blow It

Due to my work at Zylom, I read the IEBlog a lot to stay informed about the development process of IE, the major browser. Firefox is nice, and not to be overlooked, but as long as our userbase is >90% IE-based, IE is on top of my attention-list.

Too bad however that IE still has the ETAG bug with gzipped content, as I already reported early 2003!. I discovered this bug when I was working on jpcache, the lightweight php cache. Internet Explorer basically ignores the ETag headers on these pages (it does not send a If-None-Matched header back), so you will retrieve the same page over and over again on subsequent hits, which you can test yourself.

I know they are aware of this, as the Channel 9 Wiki mentions it in the IE Bugs overview.

*grumble grumble* It basically removes all the advantages of sending gzippped pages

P.S.: I still don’t smoke!
