While doing this I noticed something a little funny with the dates associated with If-modified-since. TBNL (rfc-1123-date) produces dates like "Tue, 1 Feb 2005 13:49:29 GMT" while Safari produces dates like "Tue, 01 Feb 2005 13:49:29 GMT" -- same date but you can't compare them as strings. If you look at rfc2616 section 3.3.1 there is an example that has the leading 0 on the day of month. Safari produces a header with the leading 0 for If-modified-since, so files in the first 9 days of any month will never match. FireFox appears to return whatever you send it, so it works there. I think this is probably a bug in TBNL.

Thanks for the info, I've uploaded a new version (0.3.13) which fixes this.

Stefan Scholl provided some additional info which I'll include here:

1. This bug didn't show up before because Apache silently parses and rewrites this header. Only because you sent it through Araneida which obviously just lets it through could you see the wrong format.

2. While Safari's behaviour is not strictly wrong it doesn't follow the recommendation given in the RFC to send the header back exactly as received from the server.

Thanks again, Edi. _______________________________________________ tbnl-announce site list tbnl-announce@common-lisp.net http://common-lisp.net/mailman/listinfo/tbnl-announce
