HttpServer help!

Thu Jun 6 07:48:36 EDT 2002

I am trying to get some simple example running locally on my
machine of http(server/client)  code from the book 'Python & Xml'
and I am having trouble.

if someone can look at the following script and tell me if
the problem can be because I don't have the privilege and/or
I didn't setup my system properly:
Thanks.

I am running on Linux Red Hat with python2.2.

The client code to POST:
"""
post.py
"""
from httplib import HTTP
from urllib  import quote

# establish POST data
myquote = 'This is my quote: "I think therefore I am."'

# be sure not to quote the key= sequence...
postdata = "favquote=" + quote(myquote)

print "Will POST ", len(postdata), "bytes:"
print postdata

# begin HTTP request

#req = HTTP("127.0.0.1")  # change to your IP or localhost
#req = HTTP("localhost")  # change to your IP or localhost

##### MY IP address
req = HTTP("10.16.3.132")  # change to your IP or localhost

#req.putrequest("POST", "/c8/favquote.cgi")
req.putrequest("POST",
"file:/usr/people/erict/python/srcToolskit/pythonXmlBook/c8/favquote.cgi")

.
.
.

##### That the Error after the ruprequest->"#####
Traceback (most recent call last):
  File "post.py", line 25, in ?
    req.putrequest("POST",
"file:/usr/people/erict/python/srcToolskit/pythonXmlBook/c8/favquote.cgi")

  File "/usr/people/erict/bin//lib/python2.2/httplib.py", line 453, in

    self.send(str)

  File "/usr/people/erict/bin//lib/python2.2/httplib.py", line 379, in
connect
    raise socket.error, msg

The server seems to work fine: Here is the code:  HTTPServer.py
