| now create a separate web server for their e-commerce, define,
| create and implement a SECURE web server with (at least 1024-bit
| TLS/SSL) key encryption and is subdomained as "merch.domain.com".
|
| The URL redirection/forwarder from "www.domain.com" points to:
|
| http://merch.domain.com
|
| which IMMEDIATELY has in its root web server's directory an
| "index.html" file containing:
|
| <META HTTP-EQUIV="REFRESH" CONTENT="0;
| URL=https://merch.domain.com";>
|
| Just for safety, "index.html" is symbolically linked to:
|
| index.htm index.shtml index.php index.asp ...and whatever else you
| can think of (to be safe).


Just use  a mod_rewrite rule in your webserver if you can.

|
| Does this make any sense?  To me, it's simple, esp. nowadays with
| being able to have virtual web servers such that you can literally
| have 2 different web sites served by the same server, servicing 1
| secured web server.
|
| BTW, in my book (going back to being an uber-paranoidic person),
| it's never a good idea to have a SECURED web site on the same
| server that is representative as the company's "front door".
| Basically, "www.domain.com" is Domain Web Site, Ink.'s "front door"
| (so to speak), such that if it is compromised, "merch.domain.com"
| doesn't loose it's data in the mean time.  However, because
| "merch.domain.com" is on a separate server, this now DOUBLES the
| threat of data loss, data theft, data contamination, integrity
| modification, etc.
|
| All in all, I'll take what's behind Door #2, please.
|
| Having a padlock, or a graphic representation of a padlock ON the
| web site is a nice idea, but I've found that *most*
| Internet-surfing humans have the mental and attention capacity
| (present company NOT included...) of knats.  The idea or notion of
| further dumbing down web surfing, you might as well as go back to
| days of pre-Internet and simply watch TV.  Most people's comments
| about the Internet today are that it's "too complicated, esp. with
| all of those pop-ups".  I deal with management and executives who
| *really* shouldn't even be NEAR a computer (if you can picture a
| Non Sequitur rendition with Obvious Man answering an executive, and
| the executive's head going *FOOM* when he asks if his computer
| 'thingy' is powered on).  I've had to replace entire computers of
| working with and dealing with those kinds of idiots -- but *might*
| be geniuses at legally stealing money from other businesses and
| people (which they throw words out there like "business", or
| "making money", or "building a business" -- which BTW, the last
| phrase means outsourcing their entire IT department only because
| Bill from ABC Corporation did it 2 months ago...).
|
| The whole point is "eddgoomakashun" (spelled "education") and
| teaching these people how to use a computer and the Internet in the
| first place.  In most cases, give them a Palm and a sucker and send
| 'em on their way...
|
| BTW -- JUST BECAUSE THE PADLOCK IS SHOWN DOES NOT MEAN THAT THE WEB
| SITE IS SECURED!!! 'nuf said...
