[Htmlunit-user] HTMLUnit with Recaptcha service of Google

[Vasudevan C. <vco...@gm...>]

Hi,

    I am facing a problem connecting to Recaptcha service through HTMLUnit.

   I did the following.

   1. I used FF browser to connect to Recaptcha service using a demo site
having
       the link  http://www.patcurtis.com/captcha/recaptcha_demo.php

   2. Captcha image will get displayed inside the recaptcha widget.

    3. I was pressing the reload current page continuously after the
captcha image
        is displayed. I did not get any error image even after reloading
500 times.

   I repeated the same exercise through HTMLUnit program.

   I was getting the captcha image for about 200 times of reload. But after
that
   recaptcha service was throwing an error image. The link of the error
image is
   http://www.gstatic.com/recaptcha/api/img/dos_captcha.jpg. Reloading after
   the error image throws back the same image page.

  Is there any reason for such a different behaviour through HTMLUnit?. I
was
  expecting the same behaviour to happen with HTMLUnit as normal browser.

  Does the order of HTTP request headers matter?. I see the order through
  charles proxy and see the difference.

  Any pointers to solve this issue would help me.

  Looking forward to your reply.

Regards
 Vasu
