This is a test, This is only a test...

If you edit in a URL and click the OK button this applet will retrieve the resource's response and display it below in Green... While retrieving the resource the window will turn yellow. If something goes wrong the window will turn pink. Any exception while getting the URL will be described in the screen. Pushing the No button resets the applet ready for another URL.
You can not see a sample of a URL Test Applet here:-(

See the Code and Documentation.

Also see the TextDemo Applet.

Notice that you can only access URLs on the server that served the applet. A security feature. You may also find that some browsers won't even let you do that.
