Hi Maverick,

Is there any specific reason behind bypassing captchas?

It depends on the implementation of the captcha. If it is a poorly implemented then only you will be able to bypass it.

When you try bypassing captcha, you should always check the way it works.

You can check for some of the poorly implemented captchas like .

1. Check for any randomly numeric or character value generation.

2. Intercept the request in the proxy and see if you get some thing in request and response.

3. Check whether captcha is getting refreshed eerytime you make request to the server.

Hope this helps.

Hello All,

Thanks for your suggestions . I am scrapping site using windows browser control. While doing scrapping the captcha comes and the extraction stops. I want to bypass the captcha so that the extraction continues.
