title: How to protect from tampering of query string?
body: <p>Hii,</p>
  
  <p>I have a query string like "<a href="http://project/page1.aspx?userID=5" rel="noreferrer">http://project/page1.aspx?userID=5</a>". The operation won't be performed, if the 'userID' parameter changed manually. How it is possible? </p>
