#40323 closed defect (bug) (fixed)

wp-admin/async-upload.php returns "text/html" at Content-Type

Description

When uploading image via wp-admin/async-upload.php, response-header includes "text/html" at Content-Type.

I'm creating a module only for html.
So I want to detect the response is html or not.
But this response returns text/html at header, so I cannot detect correctly.
To handle properly, I want response-header to use "application/json" or something.

If I recall correctly, wp-admin/async-upload.php is forced to return text/html due to browser incompatibilities.

Upon digging, it affects IE9 and lower - [31429].

I don't think we should be changing this header quite yet, maybe in another year or so we might be in a place where we can.

Hello @mrasu,

Changeset [45936] modified the Content-Type to text/plain in WP 5.3.0. As the request was to use something other than html, r45936 fixes this issue.

I'll close this ticket as fixed.
