title: Why WAF blocks multiple spaces?
body: <p>In my project we are using WAF. Recently I found a bug that is, when we are adding multiple spaced words in a textbox for example</p>
  <blockquote>
  <p>Hello there,       this is a multi spaced word collection
  .</p>
  </blockquote>
  <p>and trying to saving it, the WAF blocks the request, but when we try to save the text without space (more than one continues spaces) like this :</p>
  <blockquote>
  <p>Hello there, this is a multi spaced word collection .</p>
  </blockquote>
  <p>it got saved.
  I compared the formData from the network only the difference I could identify is the space. Why the WAF blocks the request? is that a built-in functionality to prevent cyber attacks?</p>
  <p>Note: If I remove the extra spaces from my UI it works fine. So am very curious to know why the WAF blocks the request?</p>
