title: ASP.NET A question about safety after writing some data to HtmlControl
body: <p>I have a hidden input on my form, and my JavaScript code writes there dynamically generated string based on the user behavior on the page.</p>
  
  <p>Later, I access to that inpput via server side code.</p>
  
  <p><strong>Many users will be using this page at the same time</strong>, so what about thread safety ?</p>
  
  <p>I mean, could it be possible that userA has an access to that string generated by userB ? Or maybe server will read that string from each user's Web Browser ?</p>
