I'm basically doing a post to a webserver in my local lan and it works perfectly until the server resets etc and then my code fires the IOErrorEvent from my listener and as this routine is on a timer (set for 30 seconds) it runs through the code again after 30 seconds and falls into a try catch and stays this way until the app is restarted. The server is sometimes glitches for a minutes and it's back on, i can test it with another app i have and it's responding just fine so i know it's in the as code. When i run through the routine and use what's below.
My question is what happens to the url loader etc after a failed ioerror. I've noticed this error is different if i unplug the server from the lan i get an ioerror and when i plug it back in then it continues to work fine, it's when the server is running and does/sends something different but i get the stream error in the ioerror listener This error.. but it's the same as the error for disconnecting the server cat5 line. This error is what gets repeated over and over based on the 30 second time. Like i said if i restart the app then it works fine again. It appears that the server is sending somthing back other than 20* commands, so what happens to flex after then occurs and it will create a "new" loader and request but will not send it after the error even though the server is ready for the requests. after some searching it appears this is a big issue and I'm looked at a site with this http://code.google.com/p/as3httpclientlib/wiki/Examples , but i'm getting somewhat tired of using 3rd party stuff to get where i'm trying to go in flex. '' already using assql and another to unzip files etc.. Please Help ! ioErrorHandler: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error.
