indicated by the url argument. The
target argument indicates in which HTML frame the
document is to be displayed.
The target argument is interpreted as follows:

contain the applet. |
"_parent" | Show in the applet's parent frame. If
the applet's frame has no parent frame,
acts the same as "_self". |
