Hi Terry,
Yes, i am getting value null.
When i am sending document through https pages my file uploading to my temp directory with filesize 0. This doesn't happen all the time. After some debug on your code we found that there were two kinds of upload process(_Addon) i.e. "xhttp" and "upload". When i upload documents through http its using "upload" and its working perfectly. When i am using that https pages its using "xhttp" and file size is 0 on my temp directory.
Can you tell me the difference between "xhttp" and "upload" and in my case why its going to "xhttp" for https.
