81110 - Proxy: FTP does not show username+password dialog (when proxy sends 401)

Status: VERIFIED FIXED

(Core Graveyard :: Networking: FTP, defect)

Description

[benc]

STEPS:

1- Configure for manual, FTP proxy.
2- Use a URL that has a user, but no password (ftp://[e-mail]/)

OBSERVED BEHAVIOR:
No page is loaded, no error is displayed, no auth is displayed.
Console does show:
"Error loading URL ftp://[e-mail]/ : 2147500037"

EXPECTED BEHAVIOR:
Set manual proxy to "direct" and send URL again to see normal behavior.
An auth dialog box should appear asking for a password.

ANALYSIS:
Similar to bug 52615, a 4xx HTTP response from the proxy is not being handled.

If you use a FTP URL that has the username and password embedded, then the ftp
request is displayed (since there is no 401 event to be handled).

In this case, the proxy has tried to use the username to connect to the ftp
server, and received a password request. The proxy uses the existing HTTP
mechanisms to request the password by returning a  401 to the client, which is
dropped.

The proxy log shows this, for example:

208.12.40.178 - - [15/May/2001:17:57:09 -0700] "GET
ftp://[e-mail]/ HTTP/1.1" 401 306 - - - - 320 144 - - 1 DIRECT
FIN - DO-NOT-CACHE
2
You can see the "401" status returned. If the client had returned a password
that was forwarded to the ftp server and accepted, the Proxy would have logged a
"200" for the transaction (Netscape Proxy Server globs up successful auth
challenges into a single log entry).

if you use a url w/ a username, the username doesn't appear in the auth dialog box.

Comm 4 does this, so I've created a 4xp report in bug 149103.
