content-negotiation

An HTTP request can include an Accept header, indicating the media type(s) of responses that the client will find acceptable. The server should honour the request by providing a response that has a Content-Type that matches (one of) the requested media type(s). A media type may include parameters . Does HTTP require that this process of content-negotiation respect parameters ? That is, if the client requests Accept: application/vnd.example; version=2 (here the version parameter has a value of 2 ), and the server can serve media-type application/vnd.example; version=1 , but not application/vnd

If a request is made to my Web API service that has a Content-Type header containing a type not supported by that service, it returns a 500 Internal Server Error status code with a message similar to the following: {"Message":"An error has occurred.","ExceptionMessage":"No MediaTypeFormatter is available to read an object of type 'MyDto' from content with media type 'application/UnsupportedContentType'.","ExceptionType":"System.InvalidOperationException","StackTrace":" at System.Net.Http.HttpContentExtensions.ReadAsAsync[T](HttpContent content, Type type, IEnumerable`1 formatters,

How can I serve an RDF representation of a Java model via Spring MVC? I have JSON and XML representations working using Spring's content negotiation mechanisms and would like to do the same for RDF. Assuming that you are using annotation driven configuration for your MVC application, this actually could be quite simple. Using the W3C's Media Types Issues for Text RDF Formats as a guide for content type specification, it's quite easy to augment your existing solution. The real question is what is your desired serialization type when a request for RDF is made? If we are utilizing Jena as the

I want to redirect users based on browser language, I figured out how to do this here, it works fine, here is the code(PHP): if(preg_match('/en-US/', $_SERVER['HTTP_USER_AGENT'])) header("location:index.php"); else header("location:http://cn.gearor.com"); The problem is I only want to redirect users from other websites or at the first visit to my website. Which means I don't want users reading some pages of my website, when they go back to index, they were redirect to other page. And I also have a link in my website, like: English or Chinese, when users click English from a Chinese page, they

I am creating a RESTful Web Service using ASP.NET MVC 4 Web API. For API access, I am returning JSON, though once I get everything working correctly, the content negotiation should work for XML and JSON by default. Since I am working towards a truly RESTful resource-centric web service, my URI's will be pointing to actual resources. I would like to take advantage of that by returning an HTML representation of the resource if Accepts: text/html comes in the request (like throwing the link in a browser). I would like to be able to take advantage of MVC 4 Web API's content negotiation to insert a

We develop a standard Java web application using Spring MVC, and have recently tried to upgrade from 3.0.6 to 3.2.0. Nearly of all our servlet responses are JSP or Json views, but there are some that are pdf requests, with extension 'pdf'. In Spring 3.0.6 we had this set up, taken from the Spring MVC documentation. <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"> <property name="mediaTypes"> <map> <entry key="pdf" value="application/pdf"/> <entry key="html" value="text/html"/> <entry key="json" value="application/json"/> </map> which worked fine, in
