|IE||myExternal.AutoScan(aDomain, anErrURL, aTarget)|
|Argument list:||aDomain||The domain address of a web site|
|anErrURL||A URL to display if aDomain is inaccessible|
|aTarget||The target window or frame to put the content into|
This mechanism is used to find a web site when you are not certain of the URL.
The registry in the client system contains a list of top level domains such as .com, .net, .org, and .edu which will be tried one at a time until a valid connection is completed.
If none of these turns out to yield a working site address, then the error URL is accessed and displayed instead.
The browser will add the leading "www." to the domain address so you might only need to specify a domain value of "wrox" for the browser to eventually connect to "www.wrox.com".
