I'm working with some ways to track the actions that come from documents I or others may write. Sometimes you see journals have things like "impact factor" and online advertising has a lot of means to evaluate ad effectiveness. I wanted to include a document identifier in a request header so that when someone clicks on a link, maybe in the bibliography, that the server can determine which document generated the user interest. However, I can't find anything about "request headers" and the "header" term gets mixed up with page headers while the quote string returns no results. I can modify the embedded links with a document specific query sting but the referer header seems better suited for this.
Thanks. Edit: to clarify, I made a local url in a tex document,

In another window, I open up a server socket with netcat and get this output ( not the lack of a referer),
