Is an empty meta refresh tag ignored or equivalent to 0?

I am working on a site where every page has this tag in the head:

<meta http-equiv="Refresh" content=""/>

The site's CMS has a meta refresh field you can set if needed, but it's not set, so this dummy refresh tag shows up on every page.

Does the browser ignore this or is it equivalent to a "0" second refresh?

Solution

  • https://www.w3.org/TR/html5/document-metadata.html#attr-meta-http-equiv-refresh describes the algorithm to process a meta refresh:

    2 .If the meta element has no content attribute, or if that attribute's value is the empty string, then abort these steps.
