httplib.HTTPSConnection problem

Hi,

I have an app that makes a https POST to a remote server that I have no 
control over.  The app runs fine in python 2.1.3 with socket.ssl 
compiled with openssl-0.9.6, however it will not run in python 2.3.3 
compiled with openssl-0.9.7d.  The script below demonstrates the problem.

============================================
import httplib
path = "/cmaonline.nsf/ePayForm?OpenForm"
body = 
'''Desc=&Bank=National&email=&creditcardholdername=fgfgg&creditcardtype=VISA&creditcardnumber=4557013000314262&ReturnHTTP=%2A&SendeMail=No&UID=0407151706104&MultiBank=No&FinalPrice=35.00&MerchantID=36&CompanyName=Bizar+Software&Mode=Test&Platform=PlainText&__Click=0&ABN=ABN+xx+xxx+xxx+xxx&Returnemail=&creditcardexpiryyear=2004&CVV=&Name=fgfgg&readers=MEL0036&creditcardexpirymonth=7&Principal='''

h = httplib.HTTPSConnection("merchant.ematters.com.au", 443)
h.debuglevel=1
h.request('POST', path, body)
resp = h.getresponse()
f = resp.fp
resp = resp.read()
f.close()
h.close()
print resp
============================================

With python 2.1, the server accepts the request correctly and has a 
proper response:

&payment_number==end
<br>&payment_reference=0407151706104=end
<br>&bank_reference==end
<br>&summary_code=707=end
<br>&response_code=707=end
<br>&response_text=GATEWAY BLOCKED=end
<br>&rcode=707=end

However, with python 2.3 I get:

<HTML>
<HEAD>
<TITLE>Error</TITLE></HEAD>
<BODY TEXT="000000">
<H1>Error 500</H1>HTTP Web Server: Invalid POST Request Exception</BODY>
</HTML>

The debuglevel printouts show that python2.1 sends the request and 
headers one at a time, where as python 2.3 sends the request and all the 
headers at once, although the actual data send is identical, so I don't 
see this as the problem.  I actually hacked httplib in my python 2.3 
installion to get _output() to send immediately rather than buffer, so 
that the debug output is identical to the python2.1 output, and that 
gives me a different error:

<HTML><HEAD><TITLE>Error</TITLE></HEAD><BODY><H1>Error 400</H1>Invalid 
request -- HOST header was not sent</BODY></HTML>

So I am suspicious that the debug output is not showing what is actually 
sent? I am really tearing my hair out with this problem because I really 
need this app to work with pyton 2.3.3, and I cannot see what else it is 
doing differently to cause this problem.

Are there any httplib/socket/ssl gurus out there that have any suggestions?
