Captcha/Server Validation on classic ASP page

Captcha/Server Validation on classic ASP page


I'm working on a site that uses classic ASP to capture form data, writing it back to a SQL server in Azure. That all works great, but we do need a captcha. Since we have DataAssist, I noticed that it had a feature for that, which is great.

I added the Captcha to the ASP form page, no problems with that. But, I cannot add a Server Validation, because it indicates that I must do this on a PHP page. I actually created a separate PHP page, but then saw that this wouldn't work because I need to select one of the form fields (on the ASP page) when creating the Server Variable through that interface.

Is there a workaround to accomplish this?

There is no tested work around for using the captcha on an ASP page. The captcha depends on a Session variable being set with the captcha answer to compare to the entered form value, and I don't think you can refer to a php session from an asp page.

You might be able to create another PHP page to return the session variable value and then use that for comparison, but I'm not even sure how that would be done. Another solution might be to use AJAX to check the value by posting to the php page.

Either way it will take some work, but is probably possible but not straightforward or easy.
