| SetDefaultCurrentValue(IWebContext, HttpRequestBase, params string[]) | `public static void SetDefaultCurrentValue(this IWebContext context, HttpRequestBase request, params string[] values)` | Sets `context.CurrentValue` to the first non-empty candidate value, but only when the request's referrer application differs from the current application; see the "Seed a default context value on cross-application arrival" operation. |
