Retrieving an Article Header Only
Retrieving an Article Header Only
The user must have some information about an article before she can know whether she wishes to read it. We mentioned earlier that some commands allow the article header and body to be transferred separately. The head command is used to request that the server transmit just the header of the specified article to the newsreader. If the user doesn't want to read this article, we haven't wasted time and network bandwidth transferring a potentially large article body unnecessarily.
Articles may be referenced using either their number (from the listgroup command) or their message identifier:
