    How works Html.BeginUmbracoForm() and Url.SurfaceAction()?

    Templates, (partial) views and macros
    Umbraco 7

    Hello, Umbracians.

    I'am trying to examine how to interract MVC controllers with html forms.

    And there are few misunderstandings about how it works.

    Here is result of Html.BeginUmbracoForm("actionName", "controllerName")

    <form action="/%D0_ManyCharsHere_0%D0%B5/" enctype="multipart/form-data" method="post"> 
    <input name="ufprt" type="hidden" value="083BE_ManyManyCharsHere_AAF">
</form>

    What a atrange value in action atribute? Looks like encrypted name of SurfaceContoller.

    And what is it: 

    <input name="ufprt" type="hidden" value="083BE_ManyManyCharsHere_AAF">

    Again, looks like some kind of encrypted data that will be send to SurfaceController.

    But, how it interract each other I have no idea. Is it a common ASP MVC mechanism or Umbraco feature?

    Hi Dmitriy

    The ufprt value is an 'Umbraco thing'

    To assist with routing of the request for a Html.BeginUmbracoForm and Url.SurfaceAction scenario.

    The ufprt contains an encrypted version of the surface controller route values.

    and if you look here:

    https://github.com/umbraco/Umbraco-CMS/blob/59f9a64e816e40e52a64e1636f743da5effb98b6/src/Umbraco.Web/Mvc/RenderRouteHandler.cs

    The value is decrypted and checked to determine whether the request being made is one to a Surface Controller or not. (SurfaceControllers kind of sit on top of MVCControllers, Umbraco needs to determine whether a request needs to be passed to a SurfaceController - https://our.umbraco.org/Documentation/Reference/Routing/surface-controllers)

    regards

    Marc

    But what for? Tell me more about reason to do it? Are there only one purpose of ufprt - distinguish who request is intended, SurfaceController or common Controller?

    What will happen if I just request SurfaceController without ufprt?
