            url url = new url(www);             httpurlconnection conexion = (httpurlconnection)url.openconnection();             string forsending = "1";             string charset = "utf-8";              string stringtosend = urlencoder.encode(forsending, charset);              conexion.setdooutput(true);             conexion.setrequestmethod("post");             outputstreamwriter out = new outputstreamwriter(             conexion.getoutputstream());              out.write("teilkauf=" + stringtosend);             out.flush();             out.close();

but doesn't work. help? thank you.

you have make post request form's action, not site form located.

form front-end backend server, when click submit browser builds request action.

so instead of posting form's location post main.php4?page=markt3art=uin=484504321483db0fc35d1e8e660b99c8&x=&y=filled=1
