http headers - Which HttpConfiguration object do I need to access to create a custom HttpParameterBinding? -

in this post, mike wasson states:

"besides parameterbindingattribute, there hook adding custom httpparameterbinding. on httpconfiguration object"

but have 3 httpconfiguration objects in web api app, namely:

public static void register(httpconfiguration config, iwindsorcontainer container) <-- in webapiconfig.cs private static void maproutes(httpconfiguration config) <-- "" public static void configurewindsor(httpconfiguration configuration) <-- in global.asax.cs 

which of these (config, config, or configuration) should use (if any)?

update

i tried this, breakpoint on "if" line:

public static void configurewindsor(httpconfiguration configuration) {     _container = new windsorcontainer();     _container.install(fromassembly.this());     _container.kernel.resolver.addsubresolver(new collectionresolver(_container.kernel, true));     var dependencyresolver = new windsordependencyresolver(_container);     configuration.dependencyresolver = dependencyresolver;      if (configuration.properties.values.count > 0) // <-- put casey jones here     {         object o = configuration.properties.values.elementat(configuration.properties.values.count - 1);         string s = o.tostring();     } } 

...but hit spot once, on server starting up, not when client sent request it...there must some event gets fired when server passes request incoming url can examined...no?

usually have 1 instance of httpconfiguration 1 globalconfiguration.configuration.

said so, that's how plugged custom binders

in global.asax

var bindermappings = new dictionary<type, type>     {         {typeof(yourmodeltype), typeof(yourmodeltypebinder)},         //....     };  config.services.add(     typeof(modelbinderprovider),     new windsormodelbinderprovider(container, bindermappings)); 

windsormodelbinderprovider

public class windsormodelbinderprovider : modelbinderprovider {     private readonly iwindsorcontainer _container;     private readonly idictionary<type, type> _bindermappings;      public windsormodelbinderprovider(iwindsorcontainer container, idictionary<type, type> bindermappings)     {         _container = container;         _bindermappings = bindermappings;     }      public override imodelbinder getbinder(httpconfiguration configuration, type modeltype)     {         imodelbinder binder = null;         if (_bindermappings.containskey(modeltype))         {             binder = _container.resolve(_bindermappings[modeltype]) imodelbinder;              if (binder == null)             {                 throw new componentnotfoundexception(modeltype);             }         }          return binder;     } }    

yourmodeltypebinder

public class yourmodeltypebinder : imodelbinder {     public yourmodeltypebinder(iyourservicetoloadyourmodeltype service)     {         //...     }      public bool bindmodel(httpactioncontext actioncontext, modelbindingcontext bindingcontext)     {         bindingcontext.model = yourcustomcodetoloadyourmodeltypeusingtheconstructordependecies(actioncontext.request);         return true;     }      private yourmodeltype yourcustomcodetoloadyourmodeltypeusingtheconstructordependecies(httprequestmessage requestmessage)     {         ...     } } 

yourmodeltypebinder resolved container(see windsormodelbinderprovider), need registered first.

after plumbing, controller may have parameter, among others, following

[modelbinder]yourmodeltype user
