Hi!
I need to define the type of user's web-browser (Opera, Ie, chrome, firefox), under which launched forms.
Tell me, please, how I do it.

This OTN Forums thread is the closest I managed to find there. Take a look.

By the way, what will you do with that information?

Honestly, I do not know. I was told to do so.
Thank you, Littlefoot, for your response.
There is another solution:

The question remains open.
I need to determine the browser in an open form in which it is running.
1) The first option to use JavaScript before launch the form.

<HTML>
<script type="text/javascript">
  var nav_name = navigator.appName + " " + navigator.appVersion;
  var url = "http://machine:8889/forms/frmservlet?config=myconfig&form=test.fmx&otherparams=BROWSER="+nav_name; 
  window.location.href = url ;
</script>
<BODY>
</BODY>
</HTML>

Then just add a BROWSER parameter to your starting form.
It is work. I can use 'User-Agent' instead of 'navigator.appName'.
But this way does not meet the requirements. The form is opened not from JavaScript, but specific method.

2) The stcond way is use HTTP Header information from within Forms.
Then I misunderstood.
I created a file

<HTML>
<BODY>
<%
out.println ("Remote address =" + request.getRemoteAddr ());
out.println ("Browser_info =" + request.getHeader ("user-agent"));
%>
</ BODY>
</ HTML>

I connect to it using the Java-bean

     String url_address = "http://172.16.1.204:8889/j2ee/remoteIP.jsp";    
     try
     {
         URL url = new URL(url_address);
         URLConnection conn = url.openConnection();
         conn.setDoOutput(true);
    
         // Get the response
         BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
         String line;  
         boolean flag_is_Browser = true;
         for(int i=0; i<100 && flag_is_Browser; i++)
         {
             line = rd.readLine();
                 System.out.println("line: " + line);
	****************************************************

Remote adres it defines true. But the user-agent " Mozilla/4.0 (Windows 7 6.1) Java/1.6.0_22 ". And no information about the browser

I also try to connect to the file through 'Utl_Http' in forms

url := 'http://172.16.1.204:8889/j2ee/remoteIP.jsp';
utl_http.set_detailed_excp_support(enable => TRUE);
		
req := Utl_Http.Begin_Request ( url => url, method => 'GET' );
UTL_HTTP.SET_HEADER(req, 'User-Agent', 'Mozilla/4.0');
resp := Utl_Http.Get_Response ( r => req );

f_out:=Client_Text_IO.Fopen('C:\a.txt', 'w');
Utl_Http.Read_Text ( r => resp, data => v_msg );	
    
Client_Text_IO.Put_Line(f_out, v_msg);
Client_Text_IO.Fclose(f_out);

Utl_Http.End_Response ( r => resp );

In this case, the user-agent is not defined (null)

Help please. Give specific and detailed response is desirable, how can I determine browser????
