Using proxy server with ROWinInetHTTPChannel

I need to enable my application which uses TROWinInetHTTPChannel for use with proxy servers. The proxy server is configured in Internet Explorer.

If this server is anonymous, is it enough that I change AccessType to “atProxy” in the TROWinInetHTTPChannel component on the client.

Are there any additional steps? I did try that, but i get an error:
Unexpected error in WinInet HTTP Channel (6)

Thanks for help.

if you have specified proxy in IE, you can use atPreconfig mode. it should be enough.
