Get file size before upload begins
Hello Friends,
I want to throw an error immediately if user is trying to upload a file of size greater than the specified limit. We are checking content-Length for this.
If Im not mistaken, for large files the issue is because of the behaviours of HTML and Java: Once the user hits on upload button, the file is included in the request body as the enctype is multipart/form-data. If the connection is slower [this application can be used over internet from user being anywhere in the world] the time taken for a file >10 MBs is considerable.
By the time the whole request is prepared and sent to the server, a lot of time elapses. Then the method you have specified can be called on the fileItem.
If the user is trying to upload a file way above the limit, like of 50MB or 100MB, then the time taken to reach till the point error gets thrown increases.
As of now we are experiencing delays in giving the size limit error message to user like the following- 10MB file ~ 10minutes. 33 MB file ~ 30 minutes and so on.
What can we do for improving this? Or is there any way to get the file size before even the upload begins?
