Redirection from 443 to 80

This is a common problem. Sharepoint doesn't know that the clients are talking HTTPS, right? When it receives the traffic, it has already been decrypted and arrives on :80. There's several ways to handle this. The quick-and-dirty way is to apply an iRule to the HTTP VIP which redirects everything to HTTPS. Something like this: when HTTP_REQUEST { HTTP::respond 301 Location "https://[HTTP::host][HTTP::uri]" } The big downside of this approach is that it will result in one unnecessary TCP round-trip, every time it's used, for every client - probably, a lot of extra hops. In other words, generally speaking it will reduce the performance of the application. What you should do, in my opinion, is to tell Sharepoint that clients are really talking HTTPS - in other words, that "SSL is offloaded". But unfortunately for you, I'm not a Sharepoint expert so I don't know how to do this. Each application is unique. But hopefully someone with Sharepoint experience will chime in.
