Thanks David.  The alpha numeric digits are generated and appended to the page by the 'addthis', a third party sharing tool (http://www.addthis.com/).

Does this mean Moz will not be able to read all pages containing this redirect behavior?

Thanks David.  I ran this URL (http://www.healthpocket.com/medicare/california-medicare) and received the following results:

HTTP 200  OK
Content-type: text/html
Date: Thu, 31 Jul 2014 20:43:16 GMT
Set-cookie: connect.sid=s%3Ac4wchmmEPyGNLoni5bmAKsSa.bSsaR4%2Bufe3qdZ0dO3HoMtQB2VY5w3%2BHWLCqEkrBarc; Path=/; HttpOnly
Vary: Accept-Encoding
X-powered-by: Express
Connection: Close

What should be my next steps?

Thank you.  But 'server settings'?  'hosting providers'?!  Isn't that a little complex consider that I've used other online seo tools and have never ran into this problem.

Also, if there are settings that I need to adjust before moz can have access of all of my pages, can I assume the other moz reports are incorrect?

thanks again.

I just signed up for MOZ Pro for the first time today.  Tried to run the 'on-page grader' tool on some of my pages but I'm getting a 'Sorry, but that URL is inaccessible' error msg.  I have verified against the robot.txt file that the pages are NOT blocking any crawlers.

Can anybody help?
