At the moment I can't get at the cookies at *all*. Can you see what
I'm doing wrong.
Here's my code (simplified) :


import ClientCookie
openfun = ClientCookie.urlopen

cj = ClientCookie.CookieJar()
req = ClientCookie.Request(theurl, txdata, txheaders)
u = openfun(req)
info = u.info()

print '<PRE>'        # This is ina CGI after all :-)
print info           # This prints the headers from the server
print
print 'Cookies :'
print cj                
for c in cj:
    print c
print '</PRE>'


Now if I set theurl to 'http://www.google.co.uk' I get the following
response :
(txdata=None, txheaders={ 'User-agent': 'Mozilla/4.0 (compatible; MSIE
5.5; Windows NT)' })

<PRE>
Cache-Control: private
Content-Type: text/html
Set-Cookie: PREF=ID=0bac71b03c6b1aa8:LD=en:TM=1092300998:LM=1092300998:S=YasA-Kgirv2NPnd9;
expires=Sun, 17-Jan-2038 19:14:07 GMT; path=/; domain=.google.co.uk
Server: GWS/2.1
Content-Length: 2901
Date: Thu, 12 Aug 2004 08:56:38 GMT
X-Cache: MISS from dav-serv.tbsmerchants.co.uk
Proxy-Connection: close


Cookies :
<ClientCookie._ClientCookie.CookieJar[]>
</PRE>

And I'm getting this consistently - I can see a cookie in the header,
but it never appears in the CookieJar - so loading and saving the
CookieJar is of no avail.

I'm sure I'm making an obvious mistake - but short of subclassing the
CookieProcessor and doing it all manually (which seems overkill) - I'm
a bit stumped.

I'll have a look in a bit... once I can get any kind of response !!

Thanks for your help.
