About URLs in AIR

Adobe AIR 1.0 and later

In HTML content running in AIR, you can use any of the following URL schemes in defining src attributes for img , frame , iframe , and script tags, in the href attribute of a link tag, or anywhere else you can provide a URL.

URL scheme	Description	Example
file	A path relative to the root of the file system.	`file:///c:/AIR Test/test.txt`
app	A path relative to the root directory of the installed application.	`app:/images`
app-storage	A path relative to the application store directory. For each installed application, AIR defines a unique application store directory, which is a useful place to store data specific to that application.	`app-storage:/settings/prefs.xml`
http	A standard HTTP request.	`http://www.adobe.com`
https	A standard HTTPS request.	`https://secure.example.com`

For more information about using URL schemes in AIR, see URI schemes .

Many of AIR APIs, including the File, Loader, URLStream, and Sound classes, use a URLRequest object rather than a string containing the URL. The URLRequest object itself is initialized with a string, which can use any of the same url schemes. For example, the following statement creates a URLRequest object that can be used to request the Adobe home page:

var urlReq = new air.URLRequest("http://www.adobe.com/");

For information about URLRequest objects see HTTP communications .
