When I use a server header checker tool ( http://www.web-caching.com/ ) to
check the web pages I get this message below. Does that look OK? Does it
have to validate? Thanks. The other images and .css stylesheet referenced
from the page all Validate and have Last-Modified information in addition to
Cache-control and Expires information.

This object has been deliberately marked stale. It doesn't have a validator
present. It doesn't have a Content-Length header present, so it can't be
used in a HTTP/1.0 persistent connection. The clock on this Web server
appears to be set incorrectly; this can cause problems when calculating
This is the code I am using in .htaccess:
# Expire .gif's 1 month from when they're accessed
ExpiresByType image/gif A2592000
# Expire everything else 1 day from when it's last modified
ExpiresDefault "modification plus 1 day"
