  • If we use the above approach to provid II8N Support then every time user has to specify lang country, it is not suggestible in web applications.
  • To overcome the above problems, we have to provide I18N Support with out depending on the user, by getting client browser provided language setup
  • When we submit a request from a client browser then browser provided lang will be send to server in the from at “accept lang” request header, here it we get “accept-language” request header value then it is possible to identify from which local the request is coming, with this, we are able to provide I18N Support without specifying lang & country by the user
  • To get a particular request header value, we have to use the following method from servlet request, public string get header (String header-name)
  • Public class I18N Servlet extends Http servlet{ = IL; Protected void do Get(Http Servlet Request request, Http Servlef Response response) Throws servlet Exception, Ioexception{


String locate=request. get header(“accept-language”);
