Hi, All

How better to arrange the downloading huge files over unstable mobile Internet ?
I think some resume is the must in this situation.

How to use resume with FTP object ?
Or how over HTTP ?

RESTRFC 3659Restart transfer from the specified point.
So, it needs after download error to get the downloaded file part size = X, and send to server extra command "REST X", to resume, instead of FTP1.Download.... ?

@Erel, what is "FTP1.Download" in Java ? Any luck to add such resume .Download2 method?
Or via Reflection over FTP1 object ?

Seems, it's not so easy to make resume by FTP-commands, if only high-level wrapper used.
OK - similar question about resume download over HTTP - what is our standard B4A solution now ?

Not sure what you mean. It is based on Apache Common Net. You can modify that source code as well.

HTTP range requests - HTTP | MDN

An HTTP Range request asks the server to send parts of a resource back to a client. Range requests are useful for various clients, including media players that support random access, data tools that require only part of a large file, and download managers that let users pause and resume a download.

Adding this header should be simple.
