Check URL

[n12taw]

I have a large number of URL's stored in my database. I wish to know if they are still valid and require to set an automatic routine to confirm any link is valid at periodic intervals. All or specific links are to be checked in the routine. If an error code is found, be it a Filemaker error (-1 to 978), an ASP error (0100 to 0246) or a URL error (100 to 505), I want to look up the error code (stored in my database) and record this in a field related to the URL. Furthermore, a counter will be incremented each time a link is found not to be responding, so, the higher the value in the counter the less reliable the link. Once the link is re-established the counter reverts to 0, 0 representing a good and valid link.
