[web2py] Re: web2py with python 2.7 and web2py running on python 3

[Tim Nyborg]

Should be, but it can depend on what other tools you're using in web 
stack.  E.g., the steps it'll take to get Apache running two different 
environments are different from the steps to get NGINX/Uwsgi, or Gunicorn.

programable as we all like :)

[web2py] Re: web2py with python 2.7 and web2py running on python 3

[Jonathan Clark]

Definitely if you're using the rocket web server. There are various ways to 
run different versions of python on the same machine but it depends on your 
OS how to do it. Once you can run different pythons, you can run different 
versions of web2py at the same time, but you will need to use different 
ports e.g. 8080, 8081 etc. to direct the traffic to the right web2py 
instance. That's without Apache.

I also run different web2py instances behind the same Apache instance on a 
virtual host, but I have set up Apache to forward virtual host one to one 
port (using .htaccess), and virtual host two to a different port. The 
rocket server in web2py in each instance is told which port it should 
respond to. So the browser looks for www.hostone.com, .htaccess forwards 
that to port number 65789, and a web2py instance is run to service requests 
to port 65789. For hosttwo, the port number changes.

Here is a snippet of a .htacces file which does what I want:

RewriteCond %{HTTP_HOST}  hostone.com$
RewriteRule ^(.*)$https://127.0.0.1:65789/$1 [P,QSA,L]

(There is another redirect which directs www.hostone.com to hostone.com).

[web2py] shareable web2py pages on linkedin

[Marco Prosperi]

hello, if I share www.mysite.com/mypage, linkedin accepts it (can show a 
preview) but if there is another level as in 
www.mysite.com/blog/my-new_article then it refuses. It seems that this 
doesn't happen if I try to share links with more levels in the url from 
wordpress websites. Do you know how to circumvent this problem with web2py? 
I tried to use blog.mysite.com/my-new-article but I can't figure out which 
should be the controller/function to manage the arg 'my-new-article' (I use 
init, default and index as default app, controller, function)

thanks in advance for hints

Marco

[web2py] Re: how to expire sessions in py4web

[Massimo Di Pierro]

Session and login information are not same. The latter is stored in the 
former. When you logout it clears the login info in the session but does 
not clear the session. There is no need. You can of course do 
session.clear() if you want.

Sessions tells py4web (or web2py) that you are the same user as before. 
auth tells who you are and what you are authorized to do.

Re: [web2py] Re: how to expire sessions in py4web

[Carlos Hanson]

Thanks. That makes sense. Unfortunately, I asked the wrong question after
trying to figure out the answer myself.

How do I force a logout after some period of time? I thought expiring the
session would do that. In web2py, I had to extend the time so my users
would stay logged in for a longer period of time. Now I I want to ensure
that aren't logged in for too long.

Thanks.
