Reciprocal Link Checker in ASP

[ColumbusOnline]

I was wondering if anyone has come across any code that I could use on my directory to check reciprocal links to make sure my link is still there? I have seen programs that can do that, but I am looking to intregrate it into my directory which is coded in ASP so that it is in my admin area.

I would really love a spider type that would start at the base URL and spider through to find the link anywhere on the website then place the location in my database. Then on a certain frequency it would go back to that webpage. I would settle for a simple one, one where you put the linkback url yourself and it just checks that one page. Any resources/help would be appreciated.

Also, is there any easyway to pull goggle PR from the page that the link resides on? that would be pretty cool too.

thanks

Thanks for the link. That is done in PHP but its a good start. I am looking for something in ASP that I can intregrate into my link manager.
