[Full-disclosure] Java Applets can connect to other hosts using HTTP 302 redirection

It seems that the java applet located on the host A is allowed to
connect to the host B using HTTP 302 redirection on the host B.

Is it a normal behaviour?

PoC:
http://www.jumperz.net/exploits/appletTest1.jsp

host A: www.gyosatu.com
host B: www.jumperz.net

In this PoC, the java applet is downloaded from www.gyosatu.com and
connects to www.jumperz.net port 1111.

Use "tcpdump port 1111" to see the packets.
