i want to check how much data has been uploaded by users like we have the ability to see download reports via Sarg reporting tool. i know we can not decrypt HTTPS traffic, i dont even want to see the file names and size. but we want to see how much data has been uploaded by who and where with only the upload over all size. like we have Sarg reporting for downloading but now we want also to track uploading data. my squid is running in proxy mode. Thanks.
