Hi Team
I tried below one to Apply rel="canonical" to PDFs (We are using AEM as a cloud service), however It is not working as expected. Could someone please help me to fix this issue

    <FilesMatch "\.pdf$">
        RewriteRule ([^/]+)\.pdf $ - [E=FILENAME:%{HTTP_HOST}%{REQUEST_URI}]
        Header set Link '<https://%{FILENAME}e>; rel="canonical"'
    </FilesMatch>

Thanks in advance 🙂

if your business allows, I would suggest to go for an easier solution with javascript

<script>
  document.addEventListener("DOMContentLoaded", function () {
    var pdfLinks = document.querySelectorAll('a[href$=".pdf"]');
    pdfLinks.forEach(function (link) {
      link.setAttribute("rel", "canonical");
    });
  });
</script>

This JavaScript code will add the rel="canonical" attribute to all <a> elements with href attributes ending in ".pdf" when the page is loaded.

Thanks @a_h_m_imrul for your solution.
I will discuss your solution with my TL on Tuesday. Could you please suggest which approach is better: this one or making changes at the Dispatcher level?

In terms of the output, you can anticipate a comparable outcome from both solutions. Nevertheless, I am not entirely convinced that achieving this through the dispatcher rewrite is straightforward. Conversely, the JavaScript solution not only offers greater ease but also provides configurability.
