Hi,
I am trying to send OPTIONS HTTP request from GAE but I am unable to do so.
I am getting this error:
java.net.ProtocolException: OPTIONS is not one of the supported http
methods: [GET, POST, HEAD, PUT, DELETE]

it is caused by following code:
...
URL remoteUrl = new URL("http://www.google.com";);
HttpURLConnection conn = (HttpURLConnection) remoteUrl.openConnection();
conn.setRequestMethod("OPTIONS");
...
Does this mean GAE is not supporting OPTIONS method at all? Or am I doing
something wrong?
Thanks in advance.
Ludvik.
