276287 - <img src=""> creates spurious server hits

Status: VERIFIED DUPLICATE of bug 225554

(Firefox :: General, defect)

Description

[chris]

When Mozilla encounters an IMG tag with an empty src attribute (<img src="">),
it makes a request from the server for an image with the same URL as the page
containing the tag.  This does not cause a problem for the client, but on the
server (on mine, at least), it triggers error handling code that causes all
kinds of grief.

If the src attribute is not specified (<img>), the problem does not manifest itself.

I believe that if an empty src is specified for the IMG tag, the browser should
make no attempt to retrieve the image.

[Phil Ringnalda (:philor)]

That's exactly what should happen: src is a URI, so src="" means the base URI,
the URL for the page. If you look closely at those two hits, you should see that
the first sends "Accept:
text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5"
and the second sends "Accept: image/png,*/*;q=0.5" because for all Firefox knows
you did that intentionally so you could do content negotiation.
