title: Tomcat 8 is not able to handle get request with '|' in query parameters?
body: <p>I am using Tomcat 8. In one case I need to handle external request coming from external source where the request has a parameters where it is separated by <code>|</code>.</p>
  
  <p>Request is looks like this:</p>
  
  <p><code>http://localhost:8080/app/handleResponse?msg=name|id|</code></p>
  
  <p>In this case I am getting following error.</p>
  
  <pre><code>java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986
