layout page to apply to this page.
PageData[key], PageData[index],
Page
Contains data shared between the page,
layout pages, and partial pages in the current
request. You can use the dynamic Page
property to access the same data, as in the
following example:
RenderBody()(Layout pages)
Renders the content of a content page that is not in
any named sections.
RenderPage(path, values)

RenderPage(path[, param1 [, param2]])

Renders a content page using the specified path and
optional extra data. You can get the values of the
extra parameters from PageData by
position (example 1) or key (example 2).

=
true|false])

Renders a content section that has a name. Set
required
to false to make a section optional.
Request.Cookies[key]
Gets or sets the value of an HTTP cookie.

Response.OutputCache(seconds
[, sliding] [, varyByParams]
