After looking around to fix things, finally I reliase that my session is always null in Umbraco.

Which is unexpected accident for umbraco, and after couple hours, luckily I found the reason and how to solve it.

Here is the reference.

Alternative not to use Captcha

 

· Reason why not to use captcha

• Most people hate filling out Captchas.
• It doesn't stop human spammers (they fill out your form manually).
• Spam software these days can break through simple Captchas.
• If you make your Captcha harder, you may block legit users.
• Blind people can't get past Captchas.

 

· Simple solution just add 1 more input field hidden by CSS – this need to be check if it is filled means it’s filled by bot.
