What about using JavaScript? Try this:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Changing location</title>
</head>
<body>
<script language="JavaScript">
function changeLanguage(lang){
var location = window.location.href;
if(location.indexOf("?") == -1){
location += "?lang=";
location += lang;
window.location = location;
} else {
var pos = location.indexOf("lang=");
if(pos != -1){
var new_location = location.substring(0, pos + 5);
new_location += lang;
window.location = new_location;
} else {
location += "&lang=";
location += lang;
window.location = location;
}
}
}
</script>
<input type="button" value="RUS" onclick="changeLanguage('ru')"/>
<input type="button" value="ENG" onclick="changeLanguage('en')"/>
</body>
</html>
It will work if you don't need the addition page (such as when dealing with
login).
Also you have to be sure, that your lang=.. parameter is in the end of
parameters line (that is true until you're not trying to add lang=..
somewhere outside). And there will be problem if your application dealing
with parameters named, for example, 'XXXlang'. All imperfections mentioned
can be removed by some little changes in script.
