How do I set the canonical header to a HTTP response?












0















I know that I can add a tag to the html head



<link rel="canonical" href="https://geoffkenyon.com/how-to-add-canonical-tag-to-http-headers">


But I want to add this information in a HTTP response header instead. What header key and value would the above tag translate to?



I plan to do this in nginx as:



location /old-link {
add_header key value;
}

  • Would this make more sense as a permanent redirect, in which case the canonical reference would be the Location header?

  • The old link needs to continue to be accessible. It is the same information in another format (pdf). So I don't want to redirect.

This adds a header successfully. I haven't yet validated that google and others understand it.



location /docs-test/Otii_Tech_Spec.pdf {
add_header Link '< href=https://geoffkenyon.com/how-to-add-canonical-tag-to-http-headers >; rel="canonical"';
}
