| Href(path [, param1 [, param2]]) | Creates a browser-compatible URL from a local file path, with optional additional path parts. |
| Html.Raw(value) | Renders value as HTML markup instead of rendering it as HTML-encoded output. |
| IsBool(), IsDateTime(), IsDecimal(), IsFloat(), IsInt() | Returns true if the value can be converted from a string to the specified type. |
| IsEmpty() | Returns true if the object or variable has no value. |
| IsPost | Returns true if the request is a POST. (Initial requests are usually a GET.) |
| Layout | Specifies the path of a 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). |
| RenderSection(sectionName [, required = true|false]) | (Layout pages) 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. |
| Request.Files[key] | Gets the files that were uploaded in the current request. |
| Request.Form[key] | Gets data that was posted in a form (as strings). Request[key] checks both the Request.Form and the Request.QueryString collections. |

| Request.Unvalidated(key) Request.Unvalidated().QueryString|Form|Cookies|Headers[key] |

| Response.AddHeader(name, value) | Adds an HTTP server header to the response. |
| Response.OutputCache(seconds [, sliding] [, varyByParams]) | Caches the page output for a specified time. Optionally set sliding to reset the timeout on each page access and varyByParams to cache different versions of the page for each different query string in the page request. |
