Detect 404 Error from CSV list

I need an application where I can upload a .CSV file of my ASINs from [login to view URL] and have it check to see if the page is vaild. [login to view URL] formats its product URLs like this: [[login to view URL]<wbr />obidos/ASIN/XXXXXXXXXXXX][1] Where the X is replaced with ASIN # from our CSV file The application then has to generate a report showing me which URLs were valid and which were not. ## Deliverables * * *This broadcast message was sent to all bidders on Monday Nov 9, 2009 3:35:55 PM: Apparently I set both the minimum and maximum bid at $100, which defeats the purpose of bidding. I've reset the minimum to "under $100" and the max remains at at $100. Sorry for the inconvenience.
