Help us confirm few things, Is https://loadandgo.test.ca managed in your LTM.
If yes, I believe you have an 80 Virtual & a 443 virtual. I could see 80 virtual is already redirecting it to 443 already.
Help us understand the 443 virtual configuration. Are you simply putting an Irule to do the redirection to your another url (BTW, I see you have missed to mask your domain, mask it if you feel its confidential).
Note 443 virtual is https. Its an encrypted tunnel. You can't do redirection stuffs unless you see make it a plain text. So offload the SSL traffic first with a clientssl profile. And then do your Irule stuff.
Let us know how it goes.
