peeringdb_server.middleware
Custom django middleware.
Classes
CacheControlMiddleware
CacheControlMiddleware(django.utils.deprecation.MiddlewareMixin)
Sets the Cache-Control s-maxage header on responses
CurrentRequestContext
CurrentRequestContext(builtins.object)
Middleware that sets the current request context.
This allows access to the current request from anywhere.
Methods
_call_
def __call__(self, request)
Call self as a function.
_init_
def __init__(self, get_response)
Initialize self. See help(type(self)) for accurate signature.
HttpResponseUnauthorized
HttpResponseUnauthorized(django.http.response.HttpResponse)
An HTTP response class with a string as content.
This content can be read, appended to, or replaced.
PDBCommonMiddleware
PDBCommonMiddleware(django.middleware.common.CommonMiddleware)
"Common" middleware for taking care of some basic operations:
- Forbid access to User-Agents in settings.DISALLOWED_USER_AGENTS
- URL rewriting: Based on the APPEND_SLASH and PREPEND_WWW settings,
append missing slashes and/or prepends missing "www."s.
- If APPEND_SLASH is set and the initial URL doesn't end with a
slash, and it is not found in urlpatterns, form a new URL by
appending a slash at the end. If this new URL is found in
urlpatterns, return an HTTP redirect to this new URL; otherwise
process the initial URL as usual.
This behavior can be customized by subclassing CommonMiddleware and
overriding the response_redirect_class attribute.
Methods
process_request
def process_request(self, request)
Check for denied User-Agents and rewrite the URL based on settings.APPEND_SLASH and settings.PREPEND_WWW
PDBPermissionMiddleware
PDBPermissionMiddleware(django.utils.deprecation.MiddlewareMixin)
Middleware that checks if the current user has the correct permissions to access the requested resource.
Methods
get_username_and_password
def get_username_and_password(self, http_auth)
Get the username and password from the HTTP auth header.
response_unauthorized
def response_unauthorized(self, request, status=None, message=None)
Return a Unauthorized response.
PDBSessionMiddleware
PDBSessionMiddleware(django.contrib.sessions.middleware.SessionMiddleware)
As PeeringDB gets a lot of repeated anonymous requests that do not store and re-use session cookies this lead to substantial amount of junk django session objects.
It was decided in #1205 that new django sessions are only to be established On the login and registration processes.
Methods
process_response
def process_response(self, request, response)
If request.session was modified, or if the configuration is to save the session every time, save the changes and set a session cookie or delete the session cookie if the session has been emptied.
