High Level Browser Detection Middleware for Turbogears 2, limits access to website only for modern browsers
Project description
About BrowserLimit
Browserlimit is a TurboGears2 extension meant to quickly limit access to a website only to modern browsers. BrowserLimit requires TurboGears2.1.4 or newer.
Installing
tgext.browerlimit can be installed both from pypi or from bitbucket:
easy_install tgext.browserlimit
should just work for most of the users
Enabling BrowserLimit
Using BrowserLimit is quite simple, you can just plug it using tgext.pluggable.
If you want to avoid using tgext.pluggable for any reason it is still possible to use tgext.browserlimit by manually setting it up. At the end of your application config/app_cfg.py import tgext.browserlimit:
import tgext.browserlimit tgext.browserlimit.plug(base_config, {})
Choosing Browser Limits
By default tgext.browserlimit will limit site access to browsers which have a fairly compatible HTML4 support, those include IE8, Chrome4, Firefox3.6, Safari3.2
This can be changed by specifying the base_config.browserlimit option inside your config/app_cfg.py before loading browserlimit. Valid values are:
MODERN -> Most modern browsers with top edge features
HTML5 -> Minimal HTML5 support like video and canvas
BASIC -> Good HTML4 support (the default)
MINIMAL -> Cover as much as possible (minimum IE version 7)
New limits can be enabled using the base_config.browserlimits option. This must be a dictionary where the KEY is the limit name and the value is a class that implements __init__(self, user_agent) and is_meth(self, environ) -> bool methods.
