curl --cookie /mydir/cookies.tmp "http://xyz.com:8080/main/rest/process?cid=29-0&pid=12&gid=29-0&type=1"

Well, without doing it all for you, start with urllib2. The relevant function is urllib2.urlopen("http://www.example.com"). If you pass a second parameter, it is treated as the data in a POST request. To do a GET request, just add url encoded parameters to the URL. urllib (without the 2) has a urlencode function if you need it.

If you need to use cookies, use cookielib. The examples for it show you how.
