I need a custom 404 page for my asp.net (c#) 2.0 site. This is the functinality I am looking for:
1. if 404 error is encountered, then show the custom message to browser based user.
2. Send me an email with the URL of the page that was requested. I also need referral, IP etc header information in the email.
THE MOST IMPORTANT REQUIREMENT is that the email should be sent to me AFTER the page has been displayed to the user. i.e. the email should be sent from some sort of page unload type event. i.e. if it takes 2 minutes to connect to the SMTP server and send an email, the end user should not need to wait. The end user should see the response immediately.? IF YOU CANOT MEET THIS LAST requirement, then DO NOT BID.
