title: PHP Form POST redirects to 403 error page by LiteSpeed Web Server
body: <p>The Web Server is LiteSpeed (looked up the phpinfo()). </p>
  
  <p>A form is to be submitted with a textarea element.</p>
  
  <p>When simple text is entered in the textarea, the form is submitted as expected.</p>
  
  <p>But for some words, the 403 page is displayed (403 page by LiteSpeed). Eg. exit, exiting etc.</p>
  
  <p>Any help is appreciated.</p>
