i.Ftp Http

Overview

The HTTP downloader in i.Ftp is a simple one shot affair primarily useful for having more control over the proxy and caching settings than you would get with a normal browser. You also have access to all the headers sent back by the server, which is useful for web developers. It supports resuming downloads which most browsers don't do, useful for large file downloads that broke connection. The HTTP downloader can not be active while an FTP connection is currently open.

Usage

Open the HTTP downloader via the HTTP->HTTP Download menu, then fill out the relevant fields.

URL The full URL of the file to download.
File The local file to download to. If you have set the URL field already and you click the "..." button you will have the filename pre-populated and all you have to do is select the right folder.
Use Proxy The proxy fields are for specifying the HTTP proxy server to use. The username / password fields are optional, some proxy servers don't need them. Currently the HTTP download doesn't support user authentication, this is not the place to put any username/password required to access the source file, but the auth for the proxy.
Resume Download The resume options control the operation of the resume download feature. If the download file already exists but is of a smaller size than the source file on the HTTP server you can resume the download to only fetch the part of the file you don't have. Note: Some servers don't support resuming downloads. The option "Roll Back" allows you to discard the last "n" KB of the file as possibly corrupt. This is useful for modem connects where you were downloading the connection dropped out. This can corrupt the end of the file. A value of 8 to 16 is useful in this case. However most of the time this roll back is not needed.
Force Cache to Refetch This option turns on the header that askes the HTTP proxy cache to refetch the document/file regardless of whether it's out of date or not. Useful if you getting an old version of the file.
