title: Is W3 Total cache compatible with Contact Form 7?
body: <p>I just using w3 total cache plugin to speedup my website. It works great in many ways like page caching, db caching, object caching, js&amp;css minification and also it reduces time taken for FBR(first byte request).</p>
  
  <p>But when i checking pagespeed test in tools.pingdom.com, It shows some unwanted url(<strong>www.mydomain.com/?_wpcf7_is_ajax_call=1&amp;_wpcf7=63</strong>) takes lot of time to complete the request which affects the performance.<p> After the deactivation of w3 cache plugin that unwanted url dissappeared. I know the cause of this issue - Because of the usage of contactform7 plugin with ajax call. But it needed w3 totalcache to eliminate caching contactform7 </p>
  <br><br>
  settings changed :
  <br>
  w3 pagecache tab-> advanced settings->never cache following pages:</p>
  
  <ol>
  <li>/.<em>[].</em></li>
  <li>/?_wpcf7_is_ajax_call=1&amp;_wpcf7=63/</li>
  </ol>
  
  <p>but no use. Any help!!!</p>
