Another case is the bandwidth consumption associated to deep linking. When linking on a Web site A an image from a Web site B, we change the way the distant site has been planned (some people say stealing bandwidth). The caching should be handle properly, but it is very often not the case. You can even create a DDOS because of current browsers implementations. On a very high traffic Web site, using a simple <img src/>. If instead of src pointing to an image, you give an URI such as an dynamic HTML page with no long caching. The site B will collapse under the traffic generated by site A with IPs coming from everywhere (people reaching the page). Why? Because Webkit and IE at least, use "Accept: */*" for IMG resources. Other browsers will do it too. So a dynamic HTML page become a downloadable resource with an IMG element. -- Karl Dubost - http://dev.opera.com/ Developer Relations & Tools, Opera Software
