           Summary: Remove avoidable network transactions in mod_proxy_ftp
           Product: Apache httpd-2
           Version: 2.3-HEAD
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: mod_proxy
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: rahul@sun.com


When a directory or a file is requested in mod_proxy_ftp, and the user has not
hinted what kind of resource it is(usual), the ftp client in mod_proxy_ftp tries
the command SIZE first, and depending on its output, CWD or RETR.

This is not required. instead, the CWD command can be used to test if the entity
is directory or not, Reducing the number of network transactions required for a
directory listing. This will not impact the normal RETR either.

Moreover SIZE command, though widely implemented, is not part of the original
FTP RFC 959.

------- Additional Comments From rahul@sun.com  2007-08-31 04:03 -------
Created an attachment (id=20750)
 --> (http://issues.apache.org/bugzilla/attachment.cgi?id=20750&action=view)
Patch to remove SIZE command.

This was part of the larger patch (41676)

Removes the SIZE command, and instead uses the output of CWD to determine if
the entity is a directory or a file.

Removes the Content-Length header insertion since it is not actually useful 
(From httpd-dev:)
If EOS is sent in the first brigade, then Content-Length is sent, other wise
Chunked encoding is set. There is no explicit control over which header is sent

for the filters.
