Description
Hello,
Using FZ 2.2.18 there is an issue when using FileZilla
in HTTP 1.1 proxy mode.
The issue is caused by the use of the CONNECT verb for
establishing the connection with ISA proxy.
The use of CONNECT verb cause ISA proxy to raise a 502
error related to SSL connection. Checking ISA logs,
show that the proxy try to establish a tunnel for
SSL...
http://www.w3.org/Protocols/rfc2616/rfc2616-
sec9.html#sec9.9
Using ftp with IE and Firefox browsers cause no
problem. An Ethereal capture shows that the GET verb
is used instead of CONNECT.
But when a tcp port is entered the request is blocked
by ISA too...
Note:
See TracTickets
for help on using tickets.
The GET command causes the proxy to handle the FTP stuff and
instead return the FTP data in form of HTML documents.
But FileZilla is not a web browser like IE or Firefox, it
needs to handle the FTP connection itself. And for that
CONNECT is needed.
