AspNetRoutingFeatureToggle

AspNetRoutingFeatureToggle is a feature toggle library based on ASP.Net routing attempting to solve A/B testing with constant URLs.

Use Case

Currently migrating a legacy ASP.Net application ?
You want to implement A/B testing ?
Maintaining public facing URLs is an explicit requirement ?
Your URLs are already managed by ASP.Net routing ?

If all of the above are true, then you might be interested by this library to succeed your migration path.

Here is how it works:

Feature toggle is based on a predicate with the RequestContext
If the toggle returns true then ExperimentalRoute is executed
Otherwise CurrentRoute is executed

Current implementation supports WebForms and MVC IRouteHandler implementations ; works with anonymous and named routes. A fluent builder helps you configure seamlessly your routes.

Examples

WebForms to WebForms

var route = FeatureToggleRouteBuilder.WithUrl("homepage")
            .WithFeatureToogle((r) => r.HttpContext.Request.IsSecureConnection)
            .WithCurrentPageRoute("~/WebForm1.aspx")
            .WithExperimentalPageRoute("~/WebForm2.aspx")
            .Build();

WebForms to MVC

var route = FeatureToggleRouteBuilder.WithUrl("offers/offer-{title}_{id}")
            .WithFeatureToogle((r) => r.HttpContext.Request.IsSecureConnection)
            .WithCurrentPageRoute("~/Pages/Offers/Details.aspx", true, 
                defaults: null, 
                constraints: new { id = @"\d+" })
            .WithExperimentalMvcRoute(
                defaults: new { controller = "Offers", action = "Details" }, 
                constraints: new { id = @"\d+" })
            .Build();

MVC to MVC

var route = FeatureToggleRouteBuilder.WithUrl("test")
            .WithFeatureToogle((r) => r.HttpContext.Request.IsSecureConnection)
            .WithCurrentMvcRoute(new { controller = "Home", action = "Index" })
            .WithExperimentalMvcRoute(new { controller = "HomeV2", action = "Index" })
            .Build();

MVC to WebForms (sounds weird I know...)

var route = FeatureToggleRouteBuilder.WithUrl("offers/offer-{title}_{id}")
            .WithFeatureToogle((r) => r.HttpContext.Request.IsSecureConnection)
            .WithCurrentMvcRoute(
                defaults: new { controller = "Offers", action = "Details" },
                constraints: new { id = @"\d+" })
            .WithExperimentalPageRoute("~/Pages/Offers/Details.aspx", true,
                defaults: null,
                constraints: new { id = @"\d+" })                
            .Build();
