title: Changing EXTJS AJAX method from GET to POST will cause any performance problems
body: <p>I have an extjs request like this:</p>
  
  <pre><code>Ext.Ajax.request({
      url: someUrl,
      method: "GET",
      params: paramArray,         
      success: function(response){
          var responseText = response.responseText;
          //DO STUFF  
      },
      failure: function(response ) {
              // DO STUFF
              }
  }); // end of ajax call
  </code></pre>
  
  <p>Now because the method is "GET", the number pf params in the url is limited. What is the best way around this? If i just change it to "POST", will it cause any side effects? (poor performance etc). The method should logically be a "GET" because it is not an update, just a fetch but to solve my ucrrent problem with parameters, I want to change to "POST".</p>
  
  <p>Unless of curse there is a standard solution to this problem.</p>
