R help - Jan 2011 - SetInternet2, RCurl and proxy

Dear all,

Using the SetInternet2(TRUE) option works wonders with R in my sealed
down work-environment. However, I'd like to use RCurl and apparently
the proxy settings are not carried over. Is it possible to figure out
the proxy-IP and port number from R after invoking SetInternet2?

No, but it should be from your browser: all SetInternet2 does is to 
switch to use Internet Explorer internals.  cURL (and hence RCurl) 
knows nothing about IE's settings.

Note that if all you need is the proxy details, then you don't need 
SetInternet2: see ?download.file.  However, many sites need to 
authenticate to the proxy ....

What does the error message say? Is this a recent version of R?
