title: What the difference between Debug and Release in ScriptManagers's ScriptMode?
body: <p>In <em>ASP.NET AJAX</em>, I can set <code>ScriptMode</code> for <code>ScriptManager</code>. 
  The <em>script mode</em> can be <em>Debug</em> or <em>Release</em>.
  What are the exact differences between them? Is it true that on <em>debug mode</em>, generated scripts won't cache on the browser while in <em>Release</em> mode they will be cached, and subsequent server access will be prevented?</p>
