Mozbar sees the 301, but no other header checker does

[CharlesRiverInteractive]

Ok, why does Mozbar see this 301 redirect, but no other checker can?

Original URL: http://www.horizon-bcbsnj.com

Current URL: http://www.horizonblue.com/

The dev  company uses meta refreshes set to zero (html), javascript redirects (randomly), and 301 redirects (asp) that can't be verified with any other header cheker other than Mozbar.

Is mozbar correct and the other checkers wrong? Or is mozbar "special" and the search engine bots do not see the 301 at all just like Rexswain, internetmarketingninjas, SEObook, webconfs, etc don't recognize the 301 either?  They all say 200 OK.

The Chrome extension Redirect Path (built by Ayima) does see this as a 301 - it's an awesome extension and very helpful, I use it all the time.

Google is definitely seeing this as a 301 redirect - when you run the info: site operator, on the URL, they show you the horizonblue URL - they def understand this -bcbsnj url has been replaced with horizon blue - check it for yourself here
