Bug 48525 – Web Inspector: Incorrectly reports warning on missing/incorrect content-type for 304s

• Status: RESOLVED
• Resolution: FIXED
• Component: Web Inspector (Deprecated)

[Derk-Jan Hartman]

I have a webrequest of the form: http://localhost/wiki/load.php?debug=true&lang=en&modules=mediawiki.legacy.commonPrint&only=styles&skin=vector

This has the Content-Type for CSS.

When I reload my page, the same request responds with a 304 Not Modified. In this case the content-type is stripped from the response header, because per http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html such responses do not have a content-type.

The inspector reports in this case: "Resource interpreted as script but transferred with MIME type text/php.", whereas it should assume the content-type of the earlier request, it apparently is assuming the content-type of the file extension.

I can confirm the presence of this issue but do not have permission to update the bug's status. In my case I was using a Python-generated CSS.
