How to locate my next URL in R?
I'm trying to log to a secured (HTTPS) server. When I use an Internet browser to enter user and password, the browser sends me to the web page corresponding to the next URL past the login screen. When I enter the user password via getURL(), I'm having a difficulty locating that next URL. The following is the R script and the exchange between the server and the client. Where is that hidden next URL?
library(RCurl) library(XML) library(bitops) options(RCurlOptions = list(cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl"))) html_form = getURL(url1, userpwd = "my_userID:my_password", verbose = TRUE)
The verbose option provides the following log on the client/server exchange:

The answer to your original question was that the redirect with 302 response is in the Location field, but all that's doing is asking you to login again!
