[R] source and localhost

[Thomas.Bock at ptb.de]

Dear List,

I have problems with the function source() using a
url of the kind:

http://localhost:5984/path/fn.R

I receive

Fehler in file(file, "r", encoding = encoding) : 
  kann Verbindung nicht öffnen
Zusätzlich: Warnmeldung:
In file(file, "r", encoding = encoding) :
  Öffnen fehlgeschlagen: HTTP Status war '502 cannotconnect'

The url itself is ok since I can:
- use a browser
- use curl
- use download.file() function
- use getURL() (out of Duncans RCurl)

furthermore it works, when I use the full host + domain name.
So I think it is about dns stuff. I get a nice:

> Sys.getenv("no_proxy")
[1] "localhost, 127.0.0.1"

and work on 32bit opensuse 11.4 with 
R version 2.13.0 (2011-04-13)

Can someone give me a hint?
Best regards
Thomas
