Adding Canonical URL to PDFs

Question

We are using AEMaaCS. We have an requirement to add canonical URL to PDFs. Please suggest me how to add it through dispatcher configuration.

you can write a rewrite rule matching you dam asset path. The rule will add a Link header to the response, with the value of the header being the canonical URL of the PDF.

Something like

Header set Link 'FILENAME; rel="canonical"'

Hi @divyat

You can try by adding the below snippet as part of the rewrite rules

In the dispatcher module you can use "/dispatcher/src/conf.d/rewrites/rewrite.rules" to add the changes

RewriteRule ([^/]+)\.pdf$ - [E=FILENAME:$1]

<FilesMatch "\.pdf$"> Header add Link '<http://www.example.com/download/%{FILENAME}e>; rel="canonical"'

</FilesMatch>

Also please refer this below link
