http2redis configuration

http2redis must be configured with a Python script based on a simple API. You just need to know about one function and two classes to get started. The :func:`~thr.http2redis.rules.add_rule` function is used to create a new rule. :func:`~thr.http2redis.rules.add_rule` takes two mandatory parameters: an instance of the :py:class:`~thr.http2redis.rules.Criteria` class and an instance of the :py:class:`~thr.http2redis.rules.Actions` class. You may also use the optional :keyword:`stop` keyword argument to tell THR that if a request matches the rule, it should ignore subsequent rules for that request.

Here is an example:

# myconfig.py

from thr.http2redis.rules import add_rule, Criteria, Actions

add_rule(Criteria(path='/forbidden'), Actions(set_status_code=403), stop=1)
add_rule(Criteria(path='/allowed'), Actions(set_status_code=200))

Using this configuration, any request made to /forbidden will trigger a 403 response code. Requests to /allowed should trigger a 200 response.

To use a configuration file, start http2redis with the --config argument:

$ http2redis --config=myconfig.py
Start http2redis on http://localhost:8888

Now you can send requests to verify that the configuration file is taken into acount:

$ curl -D - http://localhost:8888/forbidden
HTTP/1.1 403 Forbidden
[...]

$ curl -D - http://localhost:8888/allowed
HTTP/1.1 200 OK
[...]
You can’t perform that action at this time.
