How to validate the input of the forms module backend?

Hi there

I have a site that uses the forms (DW7) module for a feedback submission.

They are experiencing a great deal of spam postings to the form.

So I implemented http://www.google.com/recaptcha to validate that the user is not a bot.

But of course, as long as this validation is only javascript on the frontend, the bot is still able to bypass this check and post data to the form.

So my question is. Is there any way to extent the forms DW7 behaviour for a specific form to include backend validation through a plugin such as reCAPTCHA (which does include a .Net library)?

Best regards Bjarne

NB. I have enabled the antispam funtionality under the "Web and HTTP" --> "Security" node in the backend. This did not make a difference.

In global.asax you can catch any post to any page in Dynamicweb

Look for something in the post and implement the server part of the form.

Or upgrade to DW 8.3.... It has lots of antispam improvements.

Hi Nicolai,

Please elaborate your answer with an example (in detail if possible).

We also have this spam problem on DW7 implementations.

Thanks in advance,
