RCurl and cookies in POST requests
Hello.
I know that it's usually possible to write cookies to a cookie
file by removing the curl handle and doing a gc() call. I can do
this with getURL(), but I just can't obtain the same results with
postForm().
If I use:
curlHandle <- getCurlHandle(cookiefile=FILE, cookiejar=FILE)
and then do:
getURL(http://example.com/script.cgi, curl=curlHandle)
rm(curlHandle)
gc()
it's OK, the cookie is there. But, if I do (same handle; the
parameter is a dummy):
postForm(site, .params=list(par="cookie"), curl=curlHandle,
style="POST")...

How to set cookies in RCurl
Hi,
I am trying to access a website and read its content. The website is a
restricted access website that I access through a proxy server (which
therefore requires me to enable cookies). I have problems in allowing Rcurl
to receive and send cookies.
The following lines give me:
library(RCurl)
library(XML)
url <- "http://www.theurl.com"
content <- readHTMLTable(url)

google login via RCurl
...sed on code from
http://www.stanford.edu/~knoepfle/cgi-bin/flatpress/?x=entry:entry101220-023915
When I try this, I get back a page saying `Your browser's cookie
functionality is turned off. Please turn it on' (both on windoze and
linux). I find that the cookie file specified in
curlSetOpt(cookiefile=) does not always get created but
curlSetOpt(verbose=TRUE) shows lines such as
* Added cookie GAPS=xxx for domain www.google.com, path /accounts,
expire 1391784478
< Set-Cookie: GAPS=xxx;Path=/accounts;Expires=Fri, 07-Feb-2014
14:47:58 GMT;Secure;HttpOnly
I am behind a firewall but the verbos...

RCurl and Google Scholar's EndNote references
Hi!
I've performed a Google Scholar Search using a query, let's say "Frank
Harrell", and parsed the links to the EndNote references from the resulting
HTML code. Now I'd like to download all the references automatically. For
this, I have tried to use RCurl, but I can't seem to get it working: I
always get error code "403 Forbidden" from the web server.
