I was looking for Vary headers from the origin server. But none visible. Instead I see 1) broken cacheability headers. The Expires: header says (Date: + 360 days), and s-maxage says 360days BUT ... Last-Modified says 1970. So Last-Modified + s-maxage is already expired. NP: this is not breaking Squid which still (incorrectly) uses Expires header in preference to s-maxage. But when we fix that bug this server will start to MISS constantly. 2) Authorization: header from eclipse. Server-authenticated requests can receive cached content but require revalidation to the server to confirm that the content is legit for this user. The server is responding with a whole new response object (200) where I would expect a 304. Does the matching "HTTP Server REQUEST" to the parent peer for the eclipse transaction contain an If-Modified-Since and/or If-Match header? Amos
