Includable pages are often used as header and footers that can be included into other pages to provide uniform functionality. Basically, an includable page is a page whose includable property has been set to Yes. After creating an includable page, you can include it into another page by using the Include Page form control.

If you have an includable page within a main page, it is possible to programatically control whether the includable page is shown or not. This can be done by entering code into the Before Show event of the page where the includable page is located. In ASP, the code would be of the nature:

IncludablePageName.Visible = false

whereas in PHP, the code would be:

global $IncludablePageName;
$IncludablePageName->Enabled = false;

In Cold Fusion, the code would be:

<CFSET hideIncludablePageName = true>

In this case IncludablePageName should be replaced with the actual name of the includable page.
