Request Error Event Multiple Messages

[PatrickMcKinney1]

I've been messing around with the requesterror event.  I have a CodePen where I'm testing stuff.  If you change the URL for either service to the "bad" URL, there are multiple error messages.  

Is there a way to use a conditional statement or other method to only display the message once? For example, just using the straight service URL, as opposed to "/query" or "/exportto"? 

I know I could add a generic message, but I would like to add the service URL in the message.

the error is definitely going to fire the event every time, but you could add some logic in your handler to strip operations like `/export` and `/query` from the url and compare it to what you've already displayed and only selectively bubble up a warning to users.
