For those who stumble upon this from a search (Google) and are trying to translate to .NET and MVC code. (as in my case)
@using (Html.BeginForm("RemoveLostRolls", "Process", FormMethod.Get)) {
}
This will show a button labeled "Process" and take you to "/Process/RemoveLostRolls".
Without "FormMethod.Get" it worked, but was seen as a "post".
