I tried with synapse, it fails. Freezing form.
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i function
IsConnected(ip,port:string;delay:integer):boolean;var 
sock:TTCPBlockSocket;begin  result:=false; 
sock:=TTCPBlockSocket.create;  try    sock.NonBlockMode:=true;   
sock.Connect(ip,port);    sleep(delay);    sock.SendString(#0);   
result:=sock.LastError=0;    sock.CloseSocket;  finally    sock.free; 
end;
Are there any simple method using jHttpClient?

Of course there is, the method I use ;

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.AndroidModule1JNIPrompt(Sender: TObject);var 
clientConn: jObject;  // add uses And_jni  and add jHttpClient1
Control  response: string;  responseCode: integer;begin   
clientConn:= jHttpClient1.OpenConnection('https://forum.lazarus.freepa
scal.org/index.php/board,43.0.html');    response:=
jHttpClient1.Get(clientConn);    responseCode:=
jHttpClient1.GetResponseCode();   
jHttpClient1.Disconnect(clientConn);      if responseCode=200 then   
 begin         showmessage(response);       end      else      begin 
     showmessage('Not Connect');      end;end;

Thank you loaded, i already use your method, it freezing a bit also,
but if get using assync  it return no freezing, but dont know how to
get response code, -> i got very simple method , using webview status,
if it got arround 50-60 gettickcount onfinish it must be offline, if
it got 0 or above 150 it must be online, very fast detect.
