c# - Web API global error handling add custom header in response -

-

i wondering if possible set custom header values whenever internal server error has occurred? doing:

public class fooexceptionhandler : exceptionhandler {     public override void handle(exceptionhandlercontext context)     {         // context.result contains custom header values         context.result = new internalservererrorresult(context.request);     } }

here want set header values though appears in request response not contain it.

is there way of doing this?

it should possible creating own exception filter.

namespace myapplication.filters {     using system;     using system.net;     using system.net.http;     using system.web.http.filters;      public class customheadersfilterattribute : exceptionfilterattribute      {         public override void onexception(httpactionexecutedcontext context)         {             context.response.content.headers.add("x-customheader", "whatever...");         }     }

}

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
