Can you disable ETag-based caching but allow If-Modified-Since? A quick check of a few popular sites shows that they're using If-Modified-Since instead of ETags, probably for this reason?
While we're on the topic of browser caches, do any browsers let you easily store your cache in RAM instead of disk? Without resorting to other 'hacks' like setting the cache path to a ramdisk, that is.
- eli 13y agoIt's very unlikely that popular sites are choosing not to use ETags in order to protect privacy. If they want to track you, they just use cookies. There is no privacy risk in a site using ETags as intended; it's only when the server abuses them to act as a unique identifies. And you can actually do the same thing with if-modified-since and the date, you just get fewer bits of data to work with.
