Active Server Watcher (ASW) - easy to use tool that periodically checks given Internet resources and notifies you when they become unavailable. ASW can monitor Web pages and scripts (CGI, ASP, PHP, etc.). You are able to define a list of resources you wish to monitor. If a resource from this list becomes unavailable, ASW executes a special action (display message, write log file, execute external file, etc.). Also, for each resource you can define the periodicity of checking and number of retries. ASW detects when your computer goes offline and stops checking for resources to prevent you from the misoperation.
