UrlChecker will continue monitoring a URL whilst it is down, and when it comes back up a separate email will be sent to the user, and the process of uptime monitoring starts again. An unlimited number of domains can be defined (in the licensed version). The actual content of these emails can be defined by the user, and different email addresses can be defined for different URL's.
This software is supplied with two separate components which work in harmony. The 24x7 monitoring is carried out by a Windows Service which sits quietly in the background, whilst the configuration and visual feedback is managed via a client GUI utility.
Data can be stored either in an integral database (supplied), or in a SQL Server database (not supplied, although the script to create the database is) from where data can be extracted for further analysis and inclusion in reports etc.
