title: Remove request parameter from query string
body: <p>I have a query string that could be: </p>
  
  <pre><code>/fr/hello?language=en
  </code></pre>
  
  <p>or</p>
  
  <pre><code>/fr/welcome?param1=222&amp;param2=aloa&amp;language=en
  </code></pre>
  
  <p>or</p>
  
  <pre><code>/it/welcome?param1=222&amp;language=en&amp;param2=aa
  </code></pre>
  
  <p>I would like to remove from each query string the parameter language with its value, therefore the results would be:</p>
  
  <pre><code>/fr/hello
  </code></pre>
  
  <p>and</p>
  
  <pre><code>/fr/welcome?param1=222&amp;param2=aloa
  </code></pre>
  
  <p>and </p>
  
  <pre><code>/it/welcome?param1=222&amp;param2=aa
  </code></pre>
  
  <p>EDIT: The length of the value of the parameter could be more than 2 </p>
  
  <p>Does anybody know any good regex expression to use in String.replaceAll([regex],[replace]) ?</p>
