My code is like the following:
URLConnection cnx = address.openConnection(); cnx.setAllowUserInteraction(false); cnx.setDoOutput(true); cnx.addRequestProperty('User-Agent', 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)'); InputStream is = cnx.getInputStream(); Is it ok if I set the headers before I get the InputStream? Will my header be sent, or will the server see the default URLConnection‘s user-agent ( if any ) ?
The headers must be set prior to getting the
InputStreamto have any affect – anIllegalStateExceptionwill be thrown if the connection is already open.As far as the
User-Agentheader specifically, it should be sent if it has been set.See the URLConnection JavaDoc.
