Hi All,

Again in 'trouble' with IDL so I am consuting you. I am bad in
compurers/programing so I do apologize if the question is naive.


I use IDL under Windows. I am trying to download some spectra from:

http://das.sdss.org/DR6/data/spectro/1d_25/0270/1d/

using WEBGET function. It works BUT only when the firewall is off. I
do not want to do that of course. In header of WEBGET func I found
that I should do this:

"
; PROXY: If you are behind a firewall and have to access the net
through a
; Web proxy, set the environment variable 'http_proxy' to
point to
; your proxy server and port, e.g.
; 'setenv http_proxy=http://web-proxy.mpia-hd.mpg.de:3128'
"

1. First, I am not sure what is proxy server and port that I should
put use. At the end of the web address I gave above writes something
so I suppose I should put:

'setenv http_proxy=http://das.sdss.org:80'

Is this ok?

2. Isn't the 'setenv' a UNIX csh command? I can not use it under
Windows, right? I have Cygwin ... does it help? What I should do in my
case?



Thanks many
oliver
