title: jQuery AJAX - Provisional headers are shown chrome
body: <p>I have a registration form with 5 text fields, 15 Checkbox, and 1 input file.</p>
  <p><strong>And this appearing these errors except case 1:</strong></p>
  <p><strong>Case # 1:</strong> When envión the form without image, and without selecting a check box, and registration is done smoothly.</p>
  <p><strong>Case # 2:</strong> If I select an image and sending the form, the form stays loading, sending the request and console shows me this Provisional headers are shown.</p>
  <p><strong>Case # 3:</strong> If I select more than 9 check boxes, also shows me the Provisional mistake headers are shown.</p>
  <p>The strange thing is that everything works perfect local smoothly, selecting all options on the form, even if I select heavy images, these errors occur is on the production server.</p>
  <p><strong>Note:</strong> Which may be causing these problems? It will be server configurations? Increase the capacity of sending information in PHP etc ...</p>
  <p>This happens both Chrome and Firefox browser.</p>
