Help: How to restrict external form submissions

[compweb]

Have multiple domains sharing an online poll. I want to check the referer to make sure the submssion is coming from one of our domains.
Tried:
<%If Request.ServerVariables(&quot;HTTP_Referer&quot Not Like &quot;%mydomain.com%&quot; Then Response.End %>

Using VBscript, want to check for partial domain match. Hope you can see what I'm trying to do.

TIA for any help,
Mitch

if inStr(theString,&quot;whatYoureLookingFor&quot > 0 then
'it is in there
else
'it is not in there
end if

that function, instr, returns the position of the substring that you specify in the string, theString. So, it the return value from the function is > 0, then it's in there. If it's = 0, then it's not in there.

What you were attempting would be valid in SQL Server.

Here's the same thing as pertains to your situation:


If inStr(Request.ServerVariables(&quot;HTTP_Referer&quot, &quot;mydomain.com&quot = 0 Then
Response.End
end if



Here's some more info on the inStr() function:
