Describes a problem when you use Internet Explorer 6 SP1 to connect to a Web site, content may not be updated, and Internet Explorer may unexpectedly quit or you receive an error message.

Website Content is not Updated

This problem may occur if the Web site uses the post-check directive in an HTTP header to perform a lazy update of content on the Web page that you are viewing. For example, this problem may occur if the Web site uses the following custom HTTP header: Cache-Control: post-check=3600,pre-check=7200
If the site administrator removes this custom HTTP header, the problem does not occur.

For an update that resolves this problem, see Microsoft Knowledge Base article 834707.
