that would be a bit of overhead too -- you'd be constantly doing reads/

personally, i'd do this:
1) use a db table to maintain a list of all the people logged in as:
[ (uid,displayname,timestamp_last_action), repeat ]
2) when someone logs in / out - modify that entry , have pylons check
is this content being requested from the server each time?
try putting a print command in your base controller -- and have it
print out all the headers
my guess is that firebug is behind all this - either requesting info 2
more times , or just having a weird loop on showing source.

How are people dealing with FormEncode and International Languages?
Our project is dealing with a lot of French writers typing things like
é , which fails many formencode tests.
This is more of an 'approach' issue:
- how are you handling internationlization in Pylons from a business
standpoint
fair on some points, i disagree with others.
i'm in the US. the formencode author seems to be as well.
'internationalization' on most things seems to be limited to swapping
in text.
many of the checks, such as PlainText allow for only a subset of
ascii. anything else trips an error. short
I think Pylons should only support Authentication as in http auth that
is supported by Apache/Nginx/Etc , and things like mod_auth / ldap /
etc.
It would be nice if it supported some sort of tie-in with services
that proxy to/from it to make that auth persist.
But everything else that people do
basically, i'd love to see a pylons config option like this:
redirect_encoding= ascii
which would just do
url.encode('ascii') on urls submitted to redirect_to -- or any other
encoding standard.
we ran into a bit of a problem with our docs being utf8 and older
browsers not liking the redirect
If you're authoring them, a good place would probably be a subfolder
of config or lib of the distributions app folder.
If these are automatically generated / cached, i like to put them in
the data folder of the distribution. i also use prefixing/reverse
namespace to avoid collisions
ie:
i store a lot of stuff in config, much of which is 'framework' related
across modules.
the current way i deal with bools is this ( by storing things in
app_globals during init )
