对于POST方法，W3规范说：
If a resource has been created on the origin server,the response
SHOULD be 201 (Created) and contain an entity which describes the
status of the request and refers to the new resource,and a Location
header (see Section 10.4).
http://www.ietf.org/internet-drafts/draft-ietf-httpbis-p2-semantics-05.txt(第8.5节)
标准响应实际上似乎是向新创建的资源发送重定向。
我使用ASP.NET MVC构建我的网站，并试图遵循规范，所以创建了一个ResourceCreatedResult类：
public class ResourceCreatedResult : ActionResult
{
public string Location { get; set; }
public override void ExecuteResult(ControllerContext context)
{
context.HttpContext.Response.Clear();
context.HttpContext.Response.StatusCode = 201;
context.HttpContext.Response.ClearHeaders();
context.HttpContext.Response.AddHeader("Location",Location);
}
}
我的行为看起来像这样：
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult CreateNew(string entityStuff)
{
Entity newEntity = new Entity(entityStuff);
IEntityRepository entityRepository = ObjectFactory.GetInstance<IEntityRepository>();
entityRepository.Add(newEntity);
ActionResult result = new ResourceCreatedResult()
{ Location = Url.Action("Show",new { id = newEntity.Id }) };
return result;
}
但是，IE，Firefox和Chrome都无法重定向到新资源。我弄错了生成正确的响应，或者Web浏览器不期望这种类型的响应，而是依赖服务器发送重定向响应？
