RCurl: authentication when posting forms
Hi, Has anyone successfully used RCurl for posting data to a password-protected site? I have tired using option netrc=1 with both postForm and curlPerform (with postfields option) but can't authenticate. I would happily provide more details if some one has had some experience with this. Thanks very much. Valerie

Hi everybody, I think that I am missing something fundamental in how strings are passed from a postForm() call in R to the curl or libcurl functions underneath.

problem post request with RCurl

The data to be sent is an XML fragment. I can do this via the command line using curl: I save the XML string to a file called query.xml and then do curl -d @query.xml
