Get the value of User-agent

Use request.header["User-agent" in ASP.) to get the user Agent of the browser, you can also use the request.useragent to obtain;
Java uses Request.getheader ("User-agent") to obtain;
PHP in the appropriate use: $_server[http_user_agent];

JS in the use of navigator.useragent to obtain (the client often use it to do browser-compatible).
