I have an upload script that used to work fine until one day we noticed it magically stopped working correctly. I don't know what settings may have changed to do this but it happens like this:
I upload a file in an iframe, sending the APC_UPLOAD_PROGRESS unique ID
I fire off a javascript call on an interval until it returns done = 1
The APC returns total, current, filename, name, and done as the variables.
For some reason it lags so that it will only update current about every 6 calls on a 400 MS interval. Any ideas?
