Best protection software for web form email spam

[c676228]

Hi all,

Can you direct me or introduce me a best way to protect a web form from a
spam robot?

Thanks,

By the way, I do did search on the web.
But I don't have any experiences of using or any knowledge about whatever I
got from the web. Most of these blockers are not available to windows 2005.

I need to get some expert opinions to make sure that I get the right one.

Thanks,

In programming there is no "best way".

Why do you ask in a classic asp NG?

Asp is serverside, and has no forms.

My fault. I was reading a thread on this forum and I did here.

Hi Betty,

As other member mentioned, if the problem is ASP.NET specific, you can feel
free to post them in ASP.NET newsgroups.

For general anti-spider in web page, here are some means you can consider:

** You can use some Captcha on webpage (which require user interaction to
fill) to prevent auto-robot based web crawler from accessing your page.

#Free Captcha form-to-email script

** Someone use client-script together with server-side validation(against a
shared timestamp or something like that) to ensure the requst is not issued
from a robot.

** If the application support authentication, then make the page
protected(not allowed for unauthenticated users) will also protect robot(as
long as the robot doesn't have your site's login account).

Sincerely,

Steven Cheng
