# arc:includec

> Includes the cached ArcScript of the specified file if a cached version exists, falling back to parsing the original file otherwise.

export const siteNameShort = "Arc";

Use the `arc:includec` keyword to include the cached {siteNameShort}Script of the specified file, if one exists in the cache. Otherwise, the original file is parsed. Like traditional includes in other programming languages, `arc:includec` is replaced by the contents of the file specified in the **file** parameter.

## Parameters

* **file**: The name of the file to be included.

## Control Attributes

None

## Example

Import the cached CSS for a website's header:

```xml theme={null}
<arc:cache file="www/cache/ui/css/css.css" dependency="~/ui/css/,~/ui/img/"/>
<arc:includec file="~/ui/css/_header.css"/> 
```
