I'm trying this out on localhost, with the aim of purchasing it for a production site. I need to have the redirect page be different for different parts of the site.

I found a topic on this, dating back to 2007, where somebody wanted to set up variable pages as the redirect after captcha fail. I followed the directions on that, and I've had partial success. By "partial success" I mean that I've got the variable page redirection set up, but now the captcha image doesn't show.

In this code, the basic code, with my variable setup commented out, the captcha image shows up just fine:

'Dim myvariablepage
'myvariablepage = "loginform.asp?message=1&username="&username&"&password="&thispass
'strIncorrectCAPTCHApage = myvariablepage

Const strIncorrectCAPTCHApage = "loginform.asp?message=1"

But when I comment out the original to enable the variable page setup, the captcha image is broken:

Dim myvariablepage
myvariablepage = "loginform.asp?message=1&username="&username&"&password="&thispass
strIncorrectCAPTCHApage = myvariablepage

'Const strIncorrectCAPTCHApage = "loginform.asp?message=1"

I can toggle this back and forth, and the results are the same. What am I doing wrong here? Any help?

try doing:

Dim strIncorrectCAPTCHApage
strIncorrectCAPTCHApage = myvariablepage

Also, you can view the captcha image direct to see if there are any errors. Right click on the (missing) image and then "Properties"/"View Image Info" (depending on your browser) to get the URL.

This pointed me in the right direction, so thanks much! I needed to move all my variable definitions into the captcha config file instead of having them in the form processor page.

The below works fine for me for the two cases I've set up, and I include it here in case it might help somebody else. For the login form, I'm echoing back whatever the user filled in, since it's small. Not sure what I'll do with the contact form.

Dim myvariablepage, username, thispass, strIncorrectCAPTCHApage, whatkind
' whatkind sets up the different variable pages and comes from a hidden form field
whatkind = Request.Form("whatkind")
strIncorrectCAPTCHApage = myvariablepage

If whatkind = "loginform" then ' back to the login form
username = Request.Form("username")
thispass = Request.Form("password")
myvariablepage = "loginform.asp?message=1&username="&username&"&password="&thispass

ElseIf whatkind = "contactform" then ' back to the contact form
myvariablepage = "contactform.asp?message=2"
End if

strIncorrectCAPTCHApage = myvariablepage
