IE Redirect Fix
This is a Rack middleware that fixes an IE issue related to redirects that occurs when all of the following are true:
- Your loadbalancer is taking care of SSL and the Rails (or other) app thinks it's running straight HTTP
- Your loadbalancer rewrites the Location header HTTP 302 responses to an https address, but doesn't rewrite the message body as well.
- Your app includes multipart forms that submit with a file uploaded and then redirect with a 302
