Making certain that when you redirect http to https is happening correctly is very important. It keeps your visitors safe by encrypting everything between your website and them.
It also makes certain that Google doesn't think that you have two pieces of content that are identical. If Google thinks you have duplicate content then at best it is going to pick whichever one it thinks is the correct one, at worst Google is going to penalize you.
Don't leave it up to chance, make sure that you are correctly redirecting from Http to Https!
Google Chrome sometimes does its job too well because it tries to keep you safe by always choosing to use the Https version of pages if it knows the domain uses them.
The automatic Google Chrome redirect is normally a great feature because it keeps your security in mind, but it can be a pain when you are trying to make sure that redirects to your own site are occurring as they should be.
This will help you by teaching you how to stop Google Chrome from automatically redirecting in certain cases.
