Package: mirrors Severity: normal Hi,
I have noticed that the Etag header returned by the different ftp.us.debian.org servers on the round-robin DNS is different. This means that caches which use the Etag header to check freshness are refreshing when it is not required. Here is the result of 3 successive runs of HEAD -H 'Cache-Control: max-age=0' http://ftp.us.debian.org/debian/dists/stable/Release As you can see, the file size and modification time is constant, but ETag changes Date: Sun, 30 Mar 2008 11:33:41 GMT Accept-Ranges: bytes ETag: "f7d40ce-e369-44647be597a40" Server: Apache Content-Length: 58217 Content-Type: text/plain Last-Modified: Sat, 16 Feb 2008 14:57:37 GMT Client-Date: Sun, 30 Mar 2008 11:33:41 GMT Client-Peer: 35.9.37.225:80 Client-Response-Num: 1 Date: Sun, 30 Mar 2008 11:33:52 GMT Accept-Ranges: bytes ETag: "bab01c4-e369-44647be597a40" Server: Apache Content-Length: 58217 Content-Type: text/plain Last-Modified: Sat, 16 Feb 2008 14:57:37 GMT Client-Date: Sun, 30 Mar 2008 11:33:52 GMT Client-Peer: 128.30.2.36:80 Client-Response-Num: 1 Date: Sun, 30 Mar 2008 11:33:55 GMT Accept-Ranges: bytes ETag: "1114034-e369-be597a40" Server: Apache/2.2.3 (Debian) Content-Length: 58217 Content-Type: text/plain Last-Modified: Sat, 16 Feb 2008 14:57:37 GMT Client-Date: Sun, 30 Mar 2008 11:33:55 GMT Client-Peer: 128.30.2.36:80 Client-Response-Num: 1 Cheers, Mark -- System Information: Debian Release: testing/unstable APT prefers testing APT policy: (990, 'testing'), (400, 'stable'), (300, 'unstable') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/dash Kernel: Linux 2.6.23-rc6-m586mmx Locale: LANG=C, LC_CTYPE=iso_8859_1 (charmap=ISO-8859-1) (ignored: LC_ALL set to en_GB) -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
