Jan,

I wrote a small test program.

#include <stdio.h>

#include <curl/curl.h>
#include <curl/types.h>
#include <curl/easy.h>

int main(int argc, char **argv)
{
        CURL *curl;
        CURLcode res;
        const char* link;

        curl_global_init(CURL_GLOBAL_ALL);

        curl = curl_easy_init();
        if (curl)
        {
                link = "http://www.google.com/calendar/render?hl=nl&tab=nc";

                curl_easy_setopt(curl, CURLOPT_URL, link);
                curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1);
                curl_easy_setopt(curl, CURLOPT_MAXREDIRS, -1);
                curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);

                res = curl_easy_perform(curl);

                curl_easy_cleanup(curl);

                fprintf(stderr, "curl told us %d\n", res);
        }

        curl_global_cleanup();

        return 0;
}

I can successfully connect to google calendar, in fact, below is part of the
VERBOSE output:

Notice the "< HTTP/1.1 302 Moved Temporarily" line?

So what exactly didn't work for you?
