X-Forwarded-Prefix

[Marc Perrin]

Hi,

I've been looking at the current support for X-Forwarded headers (cf. https://code.djangoproject.com/ticket/30729 or https://code.djangoproject.com/ticket/31354 for example).

Is there any plan to deal with X-Forwarded-Prefix? Or is that header not std enough?

If not, I'm not sure what would be the best / usual way for a user to customize HttpRequest  (get_raw_uri, build_absolute_uri) to deal with it.

Thanks,

Marc

In a brief search, I could not find any docs for X-Forwarded-Prefix.

MDN documents X-Forwarded-For and others: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Forwarded-For

To customize those functions, you could use a middleware to modify requests to wrap them:

class ExampleMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        request.get_raw_uri = wrap_get_raw_uri(request.get_raw_uri)
        # ...
        return self.get_response(request)
       
def wrap_get_raw_uri(func):
    def wrapper(*args, **kwargs):
        value = func(*args, **kwargs)
        # change value appropriately
        return value
    return wrapper
