Bug 54463 – Invalid text/html mime type reported for a 304 Not Modified image/unknown resource

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit Misc.

[Terry Riegel]

I have a URI...

http://positiveaction.org/newsite/productimages/senn610THUMB

This is a jpeg image. Apache is sending it as Content-Type : image/jpeg and Safari recieves it as such. I have verified this with the Charles web debugging proxy.

On a page that includes this image via <img src="http://positiveaction.org/newsite/productimages/senn610THUMB"> I hit refresh, and the web server responds with 304 Not Modified. This is as it should be.

However, when this happens web inspector sends this warning message...

Resource interpreted as image but transferred with MIME type text/html


Thanks,

Terry Riegel

Here are the headers I received with
curl -D headers.log http://positiveaction.org/newsite/productimages/senn610THUMB

HTTP/1.1 200 OK

Content-Length: 1060

Content-Type: image/unknown

So, it is not image/jpeg but image/unknown.

On a refresh, the resource does receive the "text/html" mime type, which is presumably due to the Safari network stack, tested on Windows 7 (Chrome reports the same "image/unknown" mime type for this 304 Not Modified). This is not a Web Inspector issue per se, so I'm changing the title and component appropriately.

Got fixed as a side effect of the bug 48525 fix.
