Circumventing content protection measures or picky server configurations such as this appears to be tends to involve HTTP protocol details that are off topic here, though someone may tackle your problem anyway and report back. Once you know what your protocol needs are (perhaps with the help of the Firebug Firefox developer tools) and have read the R documentation for the functions and packages you are using, asking for clarification on the documentation would be fair game here.
I tried setting the HTTPUserAgent string using the options function [1] but that didn't help. Oh, and please read the Posting Guide mentioned at the bottom of all R-help posts, which points out that you should send plain text emails to this list. HTML is a what-you-see-is-not-necessarily-what-we-see format.
