Re: Whack of changes to archives ...

Marc,

You have to specify Last-Modified header in strict format !!!
Check please, cacheability script:


http://www.sai.msu.su/admin/cacheability/?query=http%3A%2F%2Farchives.postgresql.org%2Fpgsql-hackers%2F2004-01%2Fmsg00282.php&descend=on

Expires         -
Cache-Control         -
Last-Modified       invalid  (01/20/04 17:03:51)
ETag         -
Content-Length        - (actual size: 13593)
Server      Apache/1.3.28 (Unix) PHP/4.3.3RC1

Good tutorial on cacheability is:

http://www.mnot.net/cache_docs/

 time in a HTTP date is Greenwich Mean Time (GMT), not local time.

For example:

Expires: Fri, 30 Oct 1998 14:19:41 GMT
