This is an application written as a sample for Personal Computer World. Its purpose is to monitor the health of one or more web sites. There’s plenty that could be done to improve it, but it works as-is:

The idea is that the app checks that a list of urls, verifies that they are alive, and lets you check the content for errors.

The code is here; or you can view the repository here.

It’s the kind of thing I may improve over time; let me know if you have suggestions.
