StackInAWSGI - Missing Session

StackInAWSGI - Unknown Session
bmeyer@blu:~/stackInAWSGI/examples/gunicorn$ 

Issues:

• [x] there is an extra '/' in the returned URL, thus prohibiting finding the session
• [x] there start of the host name does returned is incorrect (http://localhost/ versus http://localhost:8081)
• [x] it's possible the session did not survive the session creation request

[BenjamenMeyer]

Confirmed that the session survives the WSGI call. However, the global dict is not truly global - it's limited to the workers (at least under gunicorn). It may be necessary to add an optional class used to create the global data hold consisting of:

• [x] Initialize the session container (dict, etc)
• [x] Add a new session
• [x] Access a session and get a response back
• [x] Remove a session
• [x] define a base class and a default implementation, with versions of uwsgi and gevent

Looking at gunicorn there doesn't seem any documentation on how to do have cross-worker communications. Contacting them on IRC via #gunicorn.

PR #12 fixes the duplicate '/' in the location url

[BenjamenMeyer]

PR #13 fixes the location URL issue; however, the issue of sessions between multiple workers still needs to be worked out.

[BenjamenMeyer]

Documenting for uwsgi and gunicorn as supporting a single worker only until this issue is resolved.
