Just wondering whether anyone can help here, have developed a custom module which allows a user to enter credentials.  The module the redirects to a page within the portal, which submits the credentials to another external site.

This works fine in non production environment, but the user is prompt with endless messages of You are about to be redirected to an insecure site, Do you want to proceed etc.....  the production environment is using the BIG-IP product from F5 for redirecting all traffice request from HTTP to HTTPS.  Most if not all menu options, links work okay, except for this module.

Any clues as to what I can do to fix it, whilst at the same time using the BIG-IP redirection rule?

Thanks.
