title: Difference between two different preview mode in Sitecore
body: <p>Today I got into weird condition. I was doing Redirect for Sitecore item over IIS rewrite module. When I preview item from publish tab preview, it is redirecting properly. But when I preview item from presentation tab preview command it is not redirecting i.e. showing item presentation.</p>
  
  <p>So there are two different preview behaviors for the same item, it strike me to think about difference between these two preview options.</p>
  
  <ol>
  <li>Under Publish tab: Preview Command</li>
  <li>Under Presentation tab: Preview Command</li>
  </ol>
  
  <p>Please don't tell me that one preview mode open in new browser tab whereas second not :)  , I am asking about feature wise difference.</p>
