URL Rewrite Rule: HTTP to HTTPS Not Working

Question

Here is my problem. I cannot get HTTP to HTTPS redirect to work using the URL Rewrite module. I am using version 2, by the way, which I understand is the latest version. I've also enabled the "Proxy Server" and Application Request Routing"
features.
I've trolled through the Internet for 2 days now for solutions to my problem, including the ones provided by the TechNet forums and by MVP Scott Forsyth. I've tried over 30 solutions, and none have resolved my issue. Granted some of the solutions I've tried
may have been repeats of others. After trying so many, I have had a hard time discerning the differences. Does it really matter, for instance if the pattern match for the {HTTPS} input is specified as
"^off$" or just "off"? I see this discrepancy (among others) everywhere. It seems like there are so many variations out there. It is quite confusing for the uninitiated and the newbies like myself to the
URL Rewrite technology. I have enabled and consulted my "Failed Request Tracing Rules" logs but cannot make any sense of the cryptic information it is providing.
I just cannot get my reverse proxy server to redirect http requests from the Internet to https to my internal web server. When a user specifies "https://server1.xxxxx.com". he is able to access the internal server via the reverse proxy (IIS) server.
But when he specifies "http://server1.xxxxx.com" he receives "Server Error 500 - Internal server error.There is a problem with the resource you are looking for, and it cannot be displayed."
At this point I am at my wits end, and am even considering configuring the protocol translation on our firewall. But this not my preference as it presents another layer of complexity, and device to troubleshoot later on. Below I've pasted my entire web.config
file with my most current version of the rule in question (in bold) for your review. I started to paste just the specific rule, but thought you might need to see the entire file in case something else may be conflicting with the rule.
Thank you in advance for your help.
