Trevor,
I did a silly as hell semaphore function called SafePut which is just a wrapper for put but it checks for a global prior to putting, if the global is set then it waits and loop, when the global is unset, it does the put url and sets the global. Don't know what happens if the put URLs are issued at the same time, I think one should implement a Queue data type and goes poping the puts when it's safe... or rev team could do that...
Cheers andre

Hi,
I have been doing some tests with web connected apps in Revolution and came across an interesting behavior with the put URL command.
It seems that if you call 'put URL' once and then issue another 'put URL' command before the first one finishes then the second one will not complete but return empty immediately, allowing the second one to finish. I came across this in the following scenario:
1) Option menu calls handler which calls 'put URL'
2) Handler called from the option menu in turn calls another handler that uses 'put URL' after a slight delay (using send command).
3) If the second handler hasn't finished downloading the requested data and the user makes another selection from the option menu then the 'put URL' handler called from the option menu will return empty immediately.
Is there any way around this (i.e. cancel previous put statement) or do I just need to modify the interface so that this collision of put statements never occurrs?
Thanks,
