If you are using Firefox, can you use something like the LiveHTTPHeaders add on to see the request for the SWF and whether the server sends back NOT MODIFIED. or the Firebug addon (which IMHO every web developper should have installee in his firefox anyway), in the Network Tab in can also show you the exact details of all HTTP transactions, of course also those started by the flash (or director shockwave) plugin. concerning cache, in firefox you can use those 2 about-URLs to get detailed infos about all cache entries, including last update and total number of fetches: about:cache?device=memory about:cache?device=disk cheers, valentin ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

are you really using glen's nav() function that returns a sprite, and
not accidently your original version?
and a remark: I'd recomemnd to avoid to sue the same variable name both

(althouight it propably works in your code as long as the nav variable
is local and the nav function is global).

maybe you shouldn't ignore thrown errors: AFAIK if the UTF8-data is not
complete (ie.. the last UTF-8 byte sequence is truncated), readUTF()
will throw an EOFError error. so if you handle this error correctly, you
might be safe?

I havn't tested, but if the socket class is well designed, the buffer
should only be flushed if readUTF() was sucessful, and therefor the

After some thought... the 2nd case (not enough data arrived)
is not a problem for your code, because the handleTcpData()
will get called again - once the rest of the data arrived.
But for the 1st case (several UTF strings arrived at once)...
Maybe I should try the following (and don't need a ByteArray):
private function handleTcpData(event:Event):void {
// KEEP EXTRACTING UTF-STRINGS
while(_socket.bytesAvailable) {
try{
var str:String = _socket.readUTF();
updateGUI(str);
}catch(e:Error){
// INCOMPLETE STRING, WILL BE READ LATER
return;
}
}
}
yes, I think that might be a good idea: the problem I saw peviously was
that if bytesAvailable0, but for some reason the try-statement fails
(and therefor bytesAvailable isn't set to 0), you would be caught in an
infinite loop, because I don't think the socket data will be updated
from outside while you are inside such an endless repeat-loop.
but by adding this return statement that leaves the loop this can't
happen anymore. good luck :-)
