The WA GET LAST URL ERROR command recovers several items of information about the last error that occurred in the Web area designated by the * and object parameters.
This information is returned in three variables:
- url: URL causing error.
- description (Mac OS only): A text describing the error (if available). If it is not possible to associate a text with the error, an empty string is returned. Under Windows, this parameter is always returned empty.
- errorCode: The error code.
- If the code is >=400, it is an error related to the HTTP protocol. For more information about this type of error, refer to the following address:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html - Otherwise, it is an error returned by the WebKit (Mac OS) or ActiveX (Windows).
