How to change the default HTTP OPTIONS parameters in Java

Question

My java snippet looks like:

...
String type = "text/plain;charset=UTF-8";
URL url = new URL("http://xxx/");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();

conn.setDoOutput(true);
conn.setRequestMethod("OPTIONS");
conn.setRequestProperty("Content-Type", type);
...

When I sniff what this sends it sends a

OPTIONS / HTTP/1.1

which appears to be the default.

However, I actually want to send

OPTIONS * HTTP/1.0

How would I do this?

You can't do that with "plain" java.net.URLConnection. Consider replacing by Apache Commons HttpClient which is less bloated and more configureable. You can force HTTP 1.0 mode by setting http.protocol.version to HttpVersion.HTTP_1_0 in HttpClient#getParams(). You can find an example in this document.
