Thanks for the answers.

There are firewall-setups and firewalls-setups! And not every firewall-setup 
demands a proxy authentication for outgoing request as our Microsoft FW / proxy 
server demands. Our proxy likes to authenticate using primary a NTLM schema, 
but 
up on a prior request it also accepts a Basic authentication schema. AND It 
does 
not support Digest.

As with Jmol, we had the same issues with the ANT GET task command unless we 
use 
our own ant launcher which created an Authenticator object to pass username and 
password; 

Also svnkit had the same issue in the beginning, unable to establish an 
outgoing 
connection via proxy server without the following java switches:

-Dhttp.proxyUser=C770817 
-Dhttp.proxyPassword=password 
-Dhttp.proxyServer=ourproxyserver.com 
-Dhttp.proxyPort=8080 
-Dhttp.auth.preference=Basic

Many internet client allows to enter the first 4 parameters, but that is 
sometimes 
insufficient if the client does not support a negotiating authentication schema 
and 
is then allowed to pass username and password. 

So often it is also used to deliver a hint via Java to have the proxy server 
informed about the preferred authentication schema which joint with username 
and 
password would be Basic.


The question I would have to Jmol developers is: which (apache) component is 
used 
to establish and maintain an outgoing http network connection? i.e. 
 
http://svn.apache.org/repos/asf/httpcomponents/httpclient/trunk

Josef,

You can easily check that this list is a very active forum, where messages are 
usually replied to very quickly.

After some days of waiting you should get the impression that no one has had 
needs or problems related to firewalls. You should not assume ignorance of 
"what a firewall is", but lack of experience with trouble in that while using 
Jmol.

>From your description and attempts, I would say that your problem may
well be a Java issue more than a Jmol issue. Maybe you can find other forums 
with more expert people in that area.

Sorry we couldn't help you, and good luck.
The Jmol community will be happy to learn from the outcome.
