today’s question involves URLLoader requests using encrypted strings.

when I encrypt a string I get the following result:

I send it in, everything seems fine on Flex’s end. But when I go to the serverside (logfiles, not allowed to change server-side code) to check what I’m getting, I end up with this:

at first glance they’re the same, but if you check closely, the + gets replaced by a whitespace…

I’ve even tried switching the + for %2B but on the server-side it gets read as %2B, it isn’t converted to a + (flex doesn’t seem to function as a browser in this case).

Any kind of insight and help on this matter would be very appreciated.

The requests are being done as follows:

public function callService(callback:String, request:String):void{
        var url:URLRequest = new URLRequest(server);
        var requestedString:String = handlePluses(request);
        url.useCache = false;
        url.contentType = contentType;
        url.method = method;
        trace("sending: " + requestedString);
        url.data += requestedString);
        serverURL.addEventListener(IOErrorEvent.IO_ERROR, treatIO);
        serverURL.dataFormat = URLLoaderDataFormat.TEXT;
        serverURL.addEventListener(Event.COMPLETE, loadData);   
        serverURL.addEventListener(Event.CONNECT, function():void{trace("connected");});
        try{        
            serverURL.load(url);
        }catch(e:ArgumentError){trace("ArgError: " + e.message);}
        catch(e:SecurityError){trace("SecError: " + e.message);}
        catch(e:TimeoutEvent){trace("===========<Timeout>===========");}
    }

    we fixed this problem by switching the + character with a subset of escaped characters like \&\#.

    this might be a problem to others attempting the same thing and trying to keep to a minimum size.
