Delphi

<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUJLTI0MTE1Nzg3D2QWBAIBD2QWAgIHDw8WAh4HVmlzaWJsZWhkZAIDDw8WAh4EVGV4dGVkZGR2NFVBFeEeY71EBQHL03G6jJXuxQ==">
<div>
  <input type="hidden" name="__VIEWSTATEGENERATOR" id="__VIEWSTATEGENERATOR" value="261583EA">
  <input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="/wEWBAL/+amRAgLs0bLrBgLs0fbZDAKM54rGBnsveKYDayDMIAFMQZrF5+2kIAdA">
</div>

There are such lines for sending.

loging.Add('__VIEWSTATE=/wEPDwUJLTI0MTE1Nzg3D2QWBAIBD2QWAgIHDw8WAh4HVmlzaWJsZWhkZAIDDw8WAh4EVGV4dGVkZGR2NFVBFeEeY71EBQHL03G6jJXuxQ==');
    loging.Add('__VIEWSTATEGENERATOR=261583EA');
    loging.Add('__EVENTVALIDATION=/wEWBAL/+amRAgLs0bLrBgLs0fbZDAKM54rGBnsveKYDayDMIAFMQZrF5+2kIAdA');

Tried so. But does not pass.
