Adding Http Request Header to a a Href Link

Make browser submit additional HTTP-Header if click on hyperlink

The only modern 'sane' option here is to use a ServiceWorker.

A ServiceWorker can intercept HTTP requests for a domain you control and decorate it with more headers.

A ServiceWorker works 'outside' of a browser tab, and if multiple tabs are open with the same website, the same serviceworker will be used for all of them.

A full tutorial on how to accomplish that is definitely too much for this answer box, but intercepting and doing stuff with HTTP requests is a big use-case, so off-site sources will usually have this as an example.

I would say that this is kind of a bad idea. If you think you need this, maybe you can handle this in a different way. A common way to do this might be using cookies instead.

Add authorization header to clicked link

Can we add http response headers directly into html pages

You can use meta to replicate some of these. Normally not the ideal solution, but look into the http-equiv attribute of meta tags. I believe a lot of these have been deprecated in newer browsers.

Examples:

<meta http-equiv="Cache-control" content="no-cache"/>

<meta http-equiv="X-Frame-Options" content="sameorigin"/>

<meta http-equiv="pragma" content="no-cache"/>

How set HTTP *Request* header programmatically (e.g. by a -tag, link -tag, or by JavaScript)?

The XMLHTTPResponse setRequestHeader() method can be used to set HTTP request headers for an AJAX request. Various JavaScript libraries expose this function in different ways. For example, with jQuery.ajax() you would set the headers property of the settings parameter.

Hyperlinks can not hold header information.

You may be able to set headers for an AJAX request, assuming the security conditions are met (same domain or CORS).
