FILE Adapter over HTTP

Hi,

Does anybody know if File Adapter woks with files over http?

For example:

I have a CSV file at http://xxx.com/file1.csv, I want to process this file and send to RFC Adapter.

Can I put "http://xxx.com/" in "Source Directory" of file sender communication channel?

Any sugestions? (FTP is not a choice)

regards,

Luiz Alberto
