To expand on EricLaw's answer about IE 9 caching redirection responses, check out this page:

Also, one thing to note about the cached redirect responses is there really is no easy way to clear them out. Clearing cache and cookies leaves them in place. There are 2 options:

• Go into IE 9 Private Mode
• Use Fiddler to clear the Wininet cache (under Tools)
