>Release:        1.3.12
>Organization:
apache
>Environment:
Linux redhat 5.1
>Description:
Some FTP server will not send anything on the FTP control channel before
the data channel has been closed by the server after a file transfer.

On these servers the transfer will not complete properly and the process
will be waiting for input on the FTP control channel forever or until killed.

>How-To-Repeat:

The site ftp://ftp.nluug.nl is one such site which gives problems when using
apache as a proxy server.  I don't know what server they are running.

Unix servers running wu_ftpd does not have any problem.
>Fix:
Move  ap_bclose(data) to the point right after ap_proxy_send_fb or
send_dir in proxy_ftp.c before the status code is requested after the
file transfer is complete.  This has fixed the problem for me.
