In this case, the "wizardry" of the scrape is based on how Foscam responds to a given URL.
Using the scrape command is the same as typing a URL into the address bar of your web browser except that, instead of displaying the web page, its HTML gets stored in {LastResult}.
In this case, we're not looking at what comes back. Sometimes you will want to look at what comes back to try to get information from the web server, which is why it's called "scrape".
You could use Launch.OpenURL to do the same thing in this case, but then you'd have a web browser window (or new tab) opening up every time you issue a Foscam speech command.
