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
