CSRF And Ignoring Basic/Digest Auth

CSRF against routers and similar devices protected by Basic or Digest auth normally raises a login popup that warns the victim. Requesting the target URL through a CSS background-image on a DIV suppresses that dialog in Internet Explorer, so a failed GET-based CSRF stays silent. Other browsers were not found to behave this way, and POST-based CSRF is unaffected.
