How do you modify http header?

[JavaVox]

Hi

I am using the following code to connect to different web sites but some will accept the connection
and some won't. I believe that the ones that won't will not do it because the JVM is not sending
the correct header info.

Vector vect = new Vector(); 
           String filename = "htmpage.html";

           String url = "http://www.genericwebsite.com";
          

          // THE NEXT CODE TRYS TO LOOK UP PAGE AND SAVE IN A FILE


             URL myurl = new URL(url);

             FileWriter fw = new FileWriter(filename);
            
             BufferedReader in = new BufferedReader(
             new InputStreamReader(
             myurl.openStream()));

             String inputLine;

             while ((inputLine = in.readLine()) != null){
               vect.addElement(inputLine);
               fw.write(inputLine);
             }

             fw.close();

I believe that one of the things I have to do is set the User-Agent but don't know how to do this.
Can anyone help? Thanks in advance.

Modify the header by setting the request property with the urlConnection object retrieved by calling URL.getConnection()

URLConnection conn = myurl.getConnection();
conn.setRequestProperty("mykey", "myvalue");
