Thanks, that helped. I changed the code to the following:

================================================
require 'net/http'
Net::HTTP.version_1_1   # declear to use 1.1 features.

url     = "xyz.mycompany.com"
port    = 3000
path    = "/scripts/isynch.dll"
account = "me"
passwd  = "notarealpassword"

Net::HTTP.start( url, port ) {|http|
  begin
    response, body = http.get( path,
      'Authorization' => 'Basic ' + ["#{account}:#{passwd}"].pack('m').strip )
      print body
  rescue Net::ProtoRetriableError => err
    if m = %r<http://([^/]+)>.match( err.response['location'] )
      host = m[1].strip
      path = m.post_match
      retry
    end
  end
}
================================================


The code works, but I get back a frame:

<HTML>
<HEAD>
 <TITLE>Modeling Request System</TITLE>
</HEAD>
<SCRIPT>
if (window != top) {top.location = location;}
</SCRIPT>
<FRAMESET cols="200,*">
<FRAMESET rows="*,132">
  <FRAME src="isynch.dll?SyncNotesTopMenu" name="sntMenuFrame">
  <FRAME src="isynch.dll?panel=TclScript&file=QuickView.tcl" name="sntQuickViewFrame" scrolling=no>
</FRAMESET>
 <FRAME name=sntOutputFrame src=isynch.dll?SyncNotesTopIntro>

</FRAMESET>
</HTML>

Is there way to automatically get the frame documents, or do
I have to search the returned text and filter out the
new paths?

Thanks
