This method of the NetIOPermission Class sets the flag that controls whether classes that possess this permission can connect back to their originating host if the codebase URL is not a file:// URL.
public void setCanConnectToNonFileURLCodeBase(boolean f);
f | If this value is true, the permission allows connections back to the originating host if the codebase URL is not a file:// URL. |
If this flag is set to true, a later "codebase" adjustment using the adjustPermission method will include the host of the codebase URL to the set of hosts that this permission can connect to.
