public sendAndLoad(url:String, target:Object, [method:String]) : Boolean
Posts variables in the my_lv object to the specified URL. The server response is downloaded,
parsed as variable data, and the resulting variables are placed in the
target object.
Variables are posted in the same manner as
LoadVars.send(). Variables are downloaded into
target in the same manner as LoadVars.load().
When using this method, consider the Flash Player security model:
For Flash Player 8:
■ Data loading is not allowed if the calling SWF file is in the local-with-file-system sandbox
and the target resource is from a network sandbox.
■ Data loading is also not allowed if the calling SWF file is from a network sandbox and the
target resource is local.
For more information, see the following:
■ Chapter 17, "Understanding Security," in Learning ActionScript 2.0 in Flash

For Flash Player 7 and later:
■ Websites can permit cross-domain access to a resource via a cross-domain policy file.
■ In SWF files of any version running in Flash Player 7 and later, url must be in exactly the
same domain. For example, a SWF file at www.someDomain.com can load data only from
sources that are also at www.someDomain.com.
In SWF files that are running in a version of the player earlier than Flash Player 7,
url must
be in the same superdomain as the SWF file that is issuing this call. A superdomain is derived
by removing the left-most component of a file's URL. For example, a SWF file at
www.someDomain.com can load data from sources at store.someDomain.com because both
files are in the same superdomain named someDomain.com.
This method is similar to
XML.sendAndLoad().
Availability: ActionScript 1.0; Flash Player 6 - Behavior changed in Flash Player 7.
