Python Cookielib with HTTP Servers that Have Incorrect Date / Timezone Set -

-

i using python , cookielib talk http server has date incorrectly set. have no control on server, fixing time not possibility. unfortunately, server's incorrect time messes cookielib because cookies appear expired.

interestingly, if go same website web browser, browser accepts cookie , gets saved. assume modern webbrowsers come across misconfigured web servers time , see date header set incorrectly, , adjust cookie expiration dates accordingly.

has come across problem before? there way of handling within python?

bad server date

i hacked solution includes live-monkey patching of urllib library. not ideal, if others find better way, please let me know:

cook_proc = urllib2.httpcookieprocessor(cookielib.lwpcookiejar()) cookie_processing_lock = threading.lock()  def _process_cookies(request, response):     '''process cookies, in way can handle servers bad      clocks set.'''     # real monkey hacking here, put in lock.     cookie_processing_lock:         # server date.         date_header = cookielib.http2time(             response.info().getheader('date') or '')         # save old cookie parsing function.         orig_parse = cookielib.parse_ns_headers         # if server date off more hour, we'll adjust it.         if date_header:             off_by = time.time() - date_header             if abs(off_by) > 3600:                 logging.warning("server off %.1f hrs."%(abs(off_by)/3600))                 # create our monkey patched                 def hacked_parse(ns_headers):                     try:                         results = orig_parse(ns_headers)                         r in results:                             r_i, (key, val) in enumerate(r):                                 if key == 'expires':                                     r[r_i] = key, val + off_by                                     logging.info("fixing bad cookie "                                         "expiration time for: %s"%r[0][0])                         logging.info("cookie results: %s", results)                         return results                     except exception e:                         logging.error("problem parse cookie: %s"%e)                         raise                 cookielib.parse_ns_headers = hacked_parse         response = cook_proc.http_response(request, response)         # make sure set cookie processor back.         cookielib.parse_ns_headers = orig_parse
