We've been trying without luck to get ETag caching working for an accelerator config.
Basically, the origin host returns an ETag with a Cache-Control of "no-cache". The end client then requests the resource again without any cache headers, but Squid does not send an "If-None-Match" header to the origin server with the latest ETag.
We've tried the same functionality with "Last-Modified" and "If-Modified-Since" which works as expected.
We've googled around heavily but it looks like the ETag functionality was done and dusted a long time ago and should be working.
Does anyone have any idea why this doesn't work?
