s3 and proxy or upload speed limit

Nov 8, 2010 at 8:03 AM

I need to limit upload speed to amazons3.
in s3 currently is not possible to specify proxy, but I saw somewhere that s3 must use Internet Explorer Settings.
I tried to use this in mu batch file:

reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /f /v ProxyEnable /t REG_DWORD /d 00000001
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /f /v ProxyServer /t REG_SZ /d

C:\>s3 list
s3.exe version 1.7 - check for updates at http://s3.codeplex.com

3 files listed

But i can't see any connections in 3proxy log file. Sometimes I see a connection. Proxy work wery well.
Why s3 not always use the proxy settings ?
