I have a request to increase the file size upload limit from existing 5 MB to 25~50MB. The functionality currently uses a VF page to upload the file to an external ftp server. We changed the external server side setting to accept the file upto 50 mb however it seems VF page still cannot upload file that exceed 8 mb. How can I increase the limit at Visualforce page? I understand that VF page has a limit of 10 mb for file upload but here I am trying to upload file through VF that redirects to another ftp location.
