http-status-code-404

Sharing the following link in facebook is returning 404 error page information instead of the page details and link even though the page exists: http://www.kentbusinessangel.co.uk/lucky-achieve-goals?sq=be-excited&src=fb To try and fix the error: I tried encoding the link to enable passing the & and ? correctly (didn't work) I created a redirect from http://www.kentbusinessangel.co.uk/lucky-achieve-goals-be-excited/src-fb to the original url (which works when you use the url in the browser, but still only shows 404 error when sharing on facebook) I created a static page at http://www

I'd like to use the following to redirect pages that are no longer present in the database to the custom 404 page: ob_start(); .... if ( !$found ): header( "Location: /404.php", true, 404 ); exit(); endif; But this actually does not redirect, but just shows an empty page (because of the exit() call before any output to the browser). I've also tried the following: if ( !$found ): header( "HTTP/1.1 404 Not Found" ); exit(); endif; With a 'ErrorDocument 404 /404.php' in my .htaccess file, but this also just shows an empty page. And if I do this: if ( !$found ): header( "HTTP/1.1 404 Not Found" );

I have the following code: @Path("/users/{id}") public class UserResource { @Autowired private UserDao userDao; @GET @Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON}) public User getUser(@PathParam("id") int id) { User user = userDao.getUserById(id); if (user == null) { throw new NotFoundException(); } return user; } If I request for a user that doesn't exists, like /users/1234 , with " Accept: application/json ", this code returns an HTTP 404 response like one would expect, but returns Content-Type sets to text/html and a body message of html. Annotation @Produces is ignored.

( SOLUTION posted at the end of the Question) I am building a Spring 4 MVC app. And it is completely configured using Java Annotations. There is no web.xml . The app is configured by using instance of AbstractAnnotationConfigDispatcherServletInitializer and WebMvcConfigurerAdapter like so, @Configuration @EnableWebMvc @ComponentScan(basePackages = {"com.example.*"}) @EnableTransactionManagement @PropertySource("/WEB-INF/properties/application.properties") public class WebAppConfig extends WebMvcConfigurerAdapter { ... } and public class WebAppInitializer extends
