That's because every time you create a SmartRequest, this line executes: cj=CookieJar() That creates a new, *empty* cookie jar, i.e. it has no knowledge of any previously set cookies. > How to avoid that? If you read the docs on the cookielib module, and in particular CookieJar objects, you will notice that CookieJar objects are described in a section that is titled: CookieJar and FileCookieJar Objects. Hmm...I wonder what the difference is between a CookieJar object and a FileCookieJar Object? ---------- FileCookieJar implements the following additional methods: save(filename=None, ignore_discard=False, ignore_expires=False) Save cookies to a file. load(filename=None, ignore_discard=False, ignore_expires=False) Load cookies from a file. -------- That seems promising. -- http://mail.python.org/mailman/listinfo/python-list
