sitemap.xml and sitemap-xml headers return html as content type

[superpoincare]

If WordPress is installed at ​https://www.example.com, then the addresses ​https://www.example.com/sitemap.xml and ​https://www.example.com/sitemap-xml send "text/html; charset=UTF-8" as the Content-Type header.

Of course these urls get redirected to wp-sitemap.xml which sends the correct header "application/xml; charset=UTF-8". Just wondering if the page before redirection should also.

Hard to see this as an enhancement in Canonical component. I's a bug in the Sitemap component, not?

This ticket is for WordPress 5.5 so this may have changed but sitemap.xml is not part of the WordPress core sitemaps. Not in 5.9 anyway... It redirects to wp-sitemap.xml

I verified the Content-Type headers for the index on wp-sitemap.xml and all sitemaps but always get application/xml; charset=UTF-8.

This issue may be no longer valid or related to a (sitemap) plugin?

Replying to RavanH:

Thanks for testing! It does issue a 302 redirect, but also sends a Content-Type: text/html; charset=UTF-8 header, which is exactly what the ticket is about. This still happens in current trunk.

I verified the Content-Type headers for the index on wp-sitemap.xml and all sitemaps but always get application/xml; charset=UTF-8.

This is also mentioned in the ticket, the header is indeed correct on actual sitemaps.

Given the lack of traction in the last 18 months, it looks like this might be an acceptable edge case and is not going to be addressed at this time. Feel free to reopen if there is still interest in working on this further.

@SergeyBiryukov you're right I did not read the last sentence of the ticket. The discussion would then be about whether a Content-Type header alongside a Location header makes any sense at all (there being no content sent) :)

Forgot to remove the milestone in my previous comment; discussion can continue on a closed ticket until there is any interest in reopening it.
