other Internet Options
in Internet Explorer Option Dialog..
I should do control from other client program, like so-called
'client-agent' program which controls the basic and most frequently used

internet options in .

So I have changed Proxy Server Port and other Internet option in my '
client-agent' program but It's doesn't apply to currently working
browser..

of course first I did change each fields in registry..

as u guess, I did only changed registry information .. Server Port and
other fields..

but currently running Internet Explorer changed it again.. and finally
it do not affect my
changes..

Internet Settings..
