C# – Castle project per session lifestyle with ASP.NET MVC

asp.net-mvcccastle-windsorioc-containersession

I'm really new to Castle Windsor IoC container. I wanted to know if theres a way to store session variables using the IoC container. I was thinking something in the line of this:

I want to have a class to store search options: 

public interface ISearchOptions{
    public string Filter{get;set;}
    public string SortOrder{get;set;}
}

public class SearchOptions{
    public string Filter{get;set;}
    public string SortOrder{get;set;}
}

And then inject that into the class that has to use it:

public class SearchController{
    private ISearchOptions _searchOptions;
    public SearchController(ISearchOptions searchOptions){
        _searchOptions=searchOptions;
    }
    ...
}

then in my web.config, where I configure castle I want to have something like:

<castle>
    <components>
        <component id="searchOptions" service="Web.Models.ISearchOptions, Web" type="Web.Models.SearchOptions, Web" lifestyle="PerSession" />
    </components>
</castle>

And have the IoC container handle the session object without having to explicitly access it myself.

How can I do this?

Thanks.

EDIT: Been doing some research. Basically, what I want is to have the a session Scoped component. I come from Java and Spring Framework and there I have session scoped beans which I think are very useful to store session data.

this might be what your looking for.

public class PerSessionLifestyleManager : AbstractLifestyleManager
    {
    private readonly string PerSessionObjectID = "PerSessionLifestyleManager_" + Guid.NewGuid().ToString();

    public override object Resolve(CreationContext context)
    {
        if (HttpContext.Current.Session[PerSessionObjectID] == null)
        {
            // Create the actual object
            HttpContext.Current.Session[PerSessionObjectID] = base.Resolve(context);
        }

        return HttpContext.Current.Session[PerSessionObjectID];
    }

    public override void Dispose()
    {
    }
}

And then add 

<component
        id="billingManager"  
        lifestyle="custom"  
        customLifestyleType="Namespace.PerSessionLifestyleManager, Namespace"  
        service="IInterface, Namespace"
        type="Type, Namespace">
</component>
