HTTP Header

Technical Q&A
1

Hi,
This may not be your issue. But I am trying to get the some data from a forwarding page. I need to get to the HttpRequest object to get to some header information. What object or what do I need to do on my EntryPoint to get this information.

Thanks,

I found this snippet of code. Should it retain the sender header information?

public class GetExample implements EntryPoint {
public static final int STATUS_CODE_OK = 200;

public static void doGet(String url) {
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET, url);

try {
  Request response = builder.sendRequest(null, new RequestCallback() {
    public void onError(Request request, Throwable exception) {
      // Code omitted for clarity
    }

    public void onResponseReceived(Request request, Response response) {
      // Code omitted for clarity
    }
  });
} catch (RequestException e) {
  // Code omitted for clarity
}

}

public void onModuleLoad() {
doGet(“/”);
}
}

Looks like the code here just redirect you. Another word, it wipe out what’s is been passed by the source.

It there a handler or something I can extends from and grab the header from the source calls?

Thanks,

What specific HTTP request? The one for the .html file that loads the application? If so, you’ll need to either turn the .html file into a .jsp or write a filter servlet that intercepts that URL, and capture the header that way, possible storing it in the session for later retrieval via an RPC.

I got to the jsp.
