Ahhh, Safari, you little orphan.

Safari was giving this message:

"Safari can’t open the page.
Too many redirects occurred trying to open “http://www.mydomain.com/?pid=1?pid=30611?pid=30611?pid=30611?pid=30611?pid=30611?pid=30611?pid=30611?pid=30611?pid=30611?pid=30611?pid=30611?pid=30611?pid=30611?pid=30611?pid=30611?pid=30611”. This might occur if you open a page that is redirected to open another page which then is redirected to open the original page."

I had to make a little switch in PHP header redirection for Safari.
From:
header("location:?pid=30611");

To:
header("location:/?pid=30611");

IIS Server Update 12/15/08

IIS Server update 12/15 added a port 443 entry to my test website, and that prevented my regular website from starting, saying a port was already in use.
Removed the port 443 (SSL) entry from my test site and all is well.
