Strange web directory listings

will google see it as duplicate content

[jsnow]

We've put a free listing on a site which seems to list the URL strange. When I do an allinurl search on Google I now get all of these:

location.example.com/ab.aspx?www.myexample.com%2Fpage.shtml

location being replaced by many different places. So there are around 100 showing up in allinurl. Has anybody else seen this and is it likely to cause problems?
