Bug 31922

Summary:	<img>/<script>/<link> tags with src=""/href="" cause request to server
Product:	WebKit	Reporter:	Nicholas C. Zakas <webkit>
Component:	Images	Assignee:	Nobody <webkit-unassigned>

Description Nicholas C. Zakas 2009-11-26 17:51:17 PST

Chrome/Safari makes another request to the page when encountering:
<img src="">
<script src="">
<link href="">

For example, if the page is hosted at http://www.example.com/dir/mypage.htm,
each of these cause another request to be made to
http://www.example.com/dir/mypage.htm. This seems like a serious bug that has
the potential to do a lot of damage to servers.

Example page:

<html>
<head>
    <title>Bad Image</title>
</head>
<body>
<img src="">
</body>
</html>

Reproducible: Always

Steps to Reproduce:
1. Create a page with one of the offending patterns.
2. Load the page while watching HTTP traffic.
Actual Results:  
Observe that there are multiple requests to the same page.

Expected Results:  
There should be only one request to the specified page.

Note: Opera doesn't fire a request under any of these circumstances and Internet
Explorer only fires a request for <img src="">, but not for the others. Firefox behaves the same as Safari/Chrome.

Why do you think it's a bug? It's exactly what the page author asked for. What kind of damage can this do to servers?

Anyway, marking as duplicate.
