public class JWebBrowser
A very plain Web Browser with minimal functionality; but still cool.
Unfortunately, the caching doesn't work for the main display, yet.Check out the multiple right-mouse-click options. :-)
At this point, the implementation is completely transient, i.e. nothing is written to disk other than what you explicitly save; so your homepage settings, cache and favorites are reset when you restart the browser.
No support for cookies (that may be the good news ;-), JavaScript, forms, etc. at this point.
There are several other limitations as this implementation is just based on the javax.swing.JEditorPane at this point. However, there are also some features that your average browser does NOT have, such as the display of the server information in the view menu.
To use a customized HTTP Agent when connecting to a web-server, you need to set the system property http.agent accordingly before using this class.
