HI, A servlet functions to upload a file from local machine to server host. But sometimes, user would close web browser or hit back button during the process of uploading a file and only part of the file was uploaded to server side. I need to remove any incomlete files but how can I check the integrity of a file. Thanks in advance. Have a nice weekend. ---Yongping
If you are using something like com.oreilly.servlet, you should find that it will throw an Exception you can catch (most likely unexpected end of part)?
It's fairly difficult to separate out (especially with more than one file, or multiple form elements) exactly how much of the POST data is 'the file'.. but what you Might attempt is to retrieve that HTTP header that tells you the size of the POST, and if your file is signifigantly smaller than this, you know it got chopped off.
