Description

When using clustered deployments, 404 errors can appear when load balancer is only configured to use sticky sessions based on JSESSIONID cookie.

 

It would be good to have cmislib to support cookies.

For 0.5.1 I could use a cookiejar in cmislib/net.py, like this:

 

{{
from cookielib import LWPCookieJar
from urllib2 import  HTTPCookieProcessor
...
class RESTService(object):
...
    def _init_(self):
        ...
        cookiejar = LWPCookieJar('/tmp/alfresco-cookies.txt')
        try:
            cokiejar.load(ignore_discard=True, ignore_expires=True)
        except IOError:
            pass}}
                  self.cookiejar = cookiejar

    def get(self, 
...
        opener = build_opener(SmartRedirectHandler(),
                              DefaultErrorHandler(),
                              ContextualBasicAuthHandler(passwordManager),
                              HTTPCookieProcessor(self.cookiejar))
        res = opener.open(request)
        self.cookiejar.save(ignore_discard=True, ignore_expires=False)
        return res
}}
 

I use a file as cookiejar because I have to share the cookies between several processes.
