17 // FTP does not have a notion of a "protocol version" but we need something for
18 // compatibility with the current Http::Message wrapping layer. We use version 1.1:
19 // * some ICAP services probably expect /1.0 or /1.1 when parsing HTTP headers;
20 // * FTP commands are sent on a "persistent by default" connection, just like
21 // HTTP/1.1. Using 1.1 leads to fewer exceptions in current code shared by
22 // HTTP and FTP.
