In terms of bandwidth, memory, CPU, etc., you should probably considering using two separate nph-verify.cgi scripts...change the column name reference for the second URL column in the copy of the nph-verify.cgi.
That is actually the way I was thinking. I guess the challenge for me is to include the data in the Admin area. With the ability to see the status of <link1> and <link2> separately with all the bells and whistles.
