in reply to Adding param to a specified URL

I'm not sure if its sufficient to simply append the string '&name=value' to a URL containing a '?', or attach '?name=value' to a URL without a '?'

Yup. :)

(If you're asking what I think you're asking, that is). Name/value pairs can be added to a GET request in just the way you suggest.

hth,
andy.

Update: Of course, this won't work if the script behind the URL is expecting to receive parameters by POST rather than GET.
