Thank you very much tilly. I appreciate your help.
Let me explain you a bit more.
I have the right name & password. But, for some reason when I require this /opt/perl/bin/lwp-request 'http://www.perlmonks.org' I have no problems. I have probelms when I do:
/opt/perl/bin/lwp-request 'https://ri2.rois.com/cgi-bin/GetSessionId.cgi?cmd=get_session_id&uid=111111&uip=1.1.1.1&gid=nlbj2'
Also, I tried the way that you told me & I get the same error messages.
For your info, if I try this 'https://ri2.rois.com/cgi-bin/GetSessionId.cgi?cmd=get_session_id&uid=111111&uip=1.1.1.1&gid=nlbj2' from my browser I have no problems ...
Thank you very much!!
