Trying to get ssl behind nginx to work

[epugh]

Description

More deubbing.

Motivation and Context

Right now, when we complete a form, we either redirect to https://localhost, but we are behind a proxy with a long int.quepid.mycompany.com domain, OR, if we redirect to https://int.quepid.mycompany.com we get the:

Unsafe redirect to "https://int.quepid.mycompany.com/search_endpoints/2", pass allow_other_host: true to redirect anyway.

error. Which I think is because Quepid thinks it's on localhost!
