title: Joomla URL params in post request
body: <p>Recently I have been playing around with Joomla. I noticed Joomla post request submits request parameters both in form fields and also in URL parameters. For example, when I clicked "Users"-->"Edit" button, a request is sent to following URL (I used Joomla demo site). Also, additional parameters are sent as form field. </p>

  <p>My question is: why does Joomla send some request parameters in request URL instead of sending all post data as form fields? What is the reason of mixing GET and POST parameters?</p>
  
  <p><strong>Update:</strong> I googled several articles about including post request params both in request string and form body. These articles (or QA pages) state that the request still is a post request; therefore, it is not mixing GET and POST. However, these articles don't provide clear reason why we shouldn't (or should) include some post request parameters in query string while including others in request body.</p>
