It's also possible to use something like Google Gears to access local files (or
some html5 equivalent?) via putting the file in a local store and accessing it
from there without the need for the server to do something.
Another possibility would be when the application is executed from the local
filesystem to use the browser-specific file handling:
function(filePath)
{
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
var file =
Components.classes["@mozilla.org/file/local;1"].createInstance(Components.interfaces.nsILocalFile);
file.initWithPath(filePath);
if(!file.exists())
return null;
var inputStream = Components.classes["@mozilla.org/network/file-
input-stream;1"].createInstance(Components.interfaces.nsIFileInputStream);
inputStream.init(file,0x01,00004,null);
var sInputStream =
Components.classes["@mozilla.org/scriptableinputstream;1"].createInstance(Components.interfaces.nsIScriptableInputStream);
sInputStream.init(inputStream);
var contents = sInputStream.read(sInputStream.available());
sInputStream.close();
inputStream.close();
return contents;
}
for Mozilla browsers.
It seems special solutions exist for mozilla, internet explorer and opera to
access files when running in a local context.
In such a use case remote request need to be cross site.
