Usenet Newsgroup Header

The header is the article information found in your posts to Usenet newsgroups. Headers for newsgroups contain the author's name, email address, when the newsgroup article was posted, the path the post took to get to your usenet server, the reply-to address, and any other relevant information about the post. Headers of usenet newsgroup messages usually contain the exact information that you need to understand what the post is about. Think of it as a subject line of an email, where it normally contains the information as to what the message will be about as well as a number in most cases for corresponding messages that are sent alongside with it. A group of Usenet newsgroup headers is often needed to download to get the entirety of the message. See the following link for more information about header lines: Article Headers
