Rewriting https to http

[Jonathan Dance]

Okay, that's what I thought, so I have updated my revision to indicate
this. Two other quick questions:

- For conventional strings (e.g. "location /images/"), is the matching
case sensitive or case insensitive? I believe they are case sensitive
but making sure.
- When does a regular expression require quotes around it? Is it
entirely optional or is there some case when you need them? The
example on the wiki did not have quotes, but in some examples (like
yours above) I've seen quotes around the regex.

Thanks!
