title: Script puzzle <script src="ajaxpage.php?emp_id=23" />?
body: <p>Very simple Ajax request taking employee id and returning the user info as HTML dumb. 
  <code>
  <br>
  <b>Request</b> ajax("employee/info?emp_id=3543")</code>
  <br/>
  <b>Response</b> <br/>id = 3543<br>name = some name</p>
  
  <p>This is just another simple JS trick to populate the UI. <br/><br/>However i do not understand how something like below is equally able to execute correctly and dump the HTML code.  <br/>
  <code>
  &lt;script type="text/javascript" src="employee/info?emp_id=3543" />
  </code></p>
  
  <p>When page encounters following code it executes like the ajax request is executed and dumps code into page. Only difference is its no more asynchronous as in case of <b>A</b>jax.
  <br/>
  <I>Questions :</i>
  <br/>Is this correct approach ? its +ves and -ves.
  <br/>Which are the correct scenarious to user it?
  <br/>Is this also means that any HTML tag taking "src" tag can be used like this?</p>
