/*
Proxy Plug-in
Features:
Times an upload to see if it appear suspiciously fast which might indicate a proxy server or anti-virus suite intercepting the upload.
If the upload seems too fast an uploadError event is fired with PROXY error code after the final uploadProgress event.
Adds a SWFUpload setting allowing you to tweak the bytes/s for triggering the error:
proxy_detect_threshold : 256000
Adds an UPLOAD_ERROR entry called PROXY:
function uploadError(file, errorCode, message) {
if (errorCode === SWFUpload.UPLOAD_ERROR.PROXY) {
alert("You might have a proxy!");
}
}
