Interesting ... this is the first line of an HTTP response (see the HTTP protocol spec
for more info), which in fact does not have a header name in front of
it.
For your purposes, starting at index value 1 is probably the right answer.

This is a cookie; presumably a session ID cookie from some servlet engine based on the
cookie name.

According to the Javadocs, you're supposed to stop iterating as soon as you get null
values -- that's how you know you have hit the last header that was
included.

What's wrong with URLConnection.setRequestProperty(String key, String value)? For
your scenario, key would be "Set-Cookie" and value would be the string you
grabbed above (at index position 3 in your trace).
If you are connecting to an "http://xxxxxx" type URL (which is likely, since cookies
are an HTTP thing), you will also need to set some other headers, and
perhaps change the request method (default is GET). The easiest way to do this is to
cast the URLConnection to an HttpURLConnection, which gives you access to
some additional functionality that is only available when you are talking HTTP.
