I was playing around with yslow, to test the wikipedia website and I noticed it complained about the enitity tags for bits.wikimedia.org Explanation of the Etag issue: http://developer.yahoo.com/performance/rules.html#etags I quickly checked with mark, and bits uses multiple apaches, so this indeed may be an issue. "I remember we looked at it in the past, but that's a while ago, and I'm not sure it was taken into account for bits either" The ETag format for Apache 1.3 and 2.x is inode-size-timestamp
It is using a double-field ETag. The first one is the size. The second one could be the timestamp, but it would be 59488257 seconds younger than expected :S
I don't see why we'd need E-Tag while we already have style versions.
