Patrick GH commented on VFS-560:
--------------------------------
I have reproduced the problem with the following code:
{code:java}public class TestPgh {
public static void main(String[] args) throws FileSystemException{
StandardFileSystemManager fileSystemManager = new
StandardFileSystemManager();
fileSystemManager.init();
FileObject srcFile =
fileSystemManager.resolveFile("https://server1.com/images/4/1/7/1/prev_14044171.jpg";);
FileObject dstFile =
fileSystemManager.resolveFile("/Users/pgh/Desktop/image.jpg");
dstFile.copyFrom(srcFile, new AllFileSelector());
fileSystemManager.close();
}
}{code}
The result was:

> File can't be downloaded if HTTP HEAD on base url fails
> -------------------------------------------------------
>
> Key: VFS-560
> URL: https://issues.apache.org/jira/browse/VFS-560
> Project: Commons VFS
> Issue Type: Bug
> Affects Versions: 2.0
> Reporter: Patrick GH
>
> When i try to download a File via HTTP a HEAD-Request on the base url is
> executed before the actual download. In my case the result is a redirect
> (HTTP 302) to another server. This server is not available due to firewall
> restrictions and so the following HEAD request fails. The actual GET request
> to retrieve the file is never performed.
> Example:
> Url: http://server1.com/files/2015/image.jpg
> 1. commons-vfs sends HEAD request to http://server1.com/ (not
> http://server1.com/files/2015/image.jpg)
> 2. Server returns HTTP 302 with redirect to http://server2.com/
> 3. commons-vfs sends HEAD request to http://server2.com/
> 4. Request fails because server2.com is not available (firewall)
> 5. image.jpg is not downloaded
> Why is this HEAD request on the base url necessary? The file can be
> downloaded directly without problems.
