        **Django middleware and log filter to attach values from the headers to every log message generated as part of a request.**
        
        **Author:** Hermann Stephane Ntsamo
        
        Example
        -------
        
        ```
        DEBUG [340d34bb4bb91ed4f45c414808a03a65] myproject.apps.myapp.views: Some log message
        DEBUG [340d34bb4bb91ed4f45c414808a03a65] myproject.apps.myapp.forms: Some other log message
        ```
        
        
        Installation and usage
        ----------------------
        
        First, install the package: `pip install django-log-labeler`
        
        Add the middleware to your `MIDDLEWARE_CLASSES` setting.
        
        ```python
        MIDDLEWARE_CLASSES = (
            'log_labeler.middleware.HeaderToLabelMiddleware',
            # ... other middleware goes here
        )
        ```
        
        Add the `log_labeler.filters.HeaderToLabelFilter` to your `LOGGING` setting. Update your `formatters` to include the header names you want appearing in the log message. Add a handler to output the messages (eg to the console), and finally attach the handler to your application's logger.
        
        An example `LOGGING` setting is below:
        
        ```python
        LOG_LABEL_REQUEST_SETTING = {
            "request_id": "HTTP_X_REQUEST_ID"
        }
        
        MAX_REQUEST_RESPONSE_SIZE = 500
        
        DEFAULT_LOG_LEVEL = "INFO"
        
        NIM_DJANGO_REQUEST_LOG_LEVEL_NAME = "HTTP_NIM_CORRELATION_ID"
        
        LOG_LABEL_EXCLUDE_LOG_LIST = [
            "gunicorn.access"
        ]
        
        LOG_LABEL_OBFUSCATE = {
            "headers": ["Authorization"],
            "body": {
                "(?i)(\\<(\\w+\\:)?password.*\\>).+(\\<\\/(\\w+\\:)?password.*\\>)": r"\1[--HIDDEN--]\3",
                "(?i)(\\<(\\w+\\:)?session.*\\>).+(\\<\\/(\\w+\\:)?session.*\\>)": r"\1[--HIDDEN--]\3",
                "(?i)(\\<(\\w+\\:)?token.*\\>).+(\\<\\/(\\w+\\:)?token.*\\>)": r"\1[--HIDDEN--]\3",
                "(?i)(\\??password.*)=(.+)(\\&?)": r"\1[--HIDDEN--]\3",
                "(?i)(\\??token.*)=(.+)(\\&?)": r"\1[--HIDDEN--]\3",
                "(?i)(.+\\\".*token.*\\\"\\s*\\:\\s*\\\")(.+)(\\\"(\\,|\\}).+)": r"\1[--HIDDEN--]\3",
            },
            "response": {
                "(?i)(\\<(\\w+\\:)?password.*\\>).+(\\<\\/(\\w+\\:)?password.*\\>)": r"\1[--HIDDEN--]\3",
                "(?i)(\\<(\\w+\\:)?session.*\\>).+(\\<\\/(\\w+\\:)?session.*\\>)": r"\1[--HIDDEN--]\3",
                "(?i)(\\<(\\w+\\:)?token.*\\>).+(\\<\\/(\\w+\\:)?token.*\\>)": r"\1[--HIDDEN--]\3",
                "(?i)(\\??password.*)=(.+)(\\&?)": r"\1[--HIDDEN--]\3",
                "(?i)(\\??token.*)=(.+)(\\&?)": r"\1[--HIDDEN--]\3",
                "(?i)(.+\\\".*token.*\\\"\\s*\\:\\s*\\\")(.+)(\\\"(\\,|\\}).+)": r"\1[--HIDDEN--]\3",
            }
        }
        
        
        LOGGING = {
            'version': 1,
            'disable_existing_loggers': False,
            'filters': {
                'request_id': {
                    '()': 'log_labeler.filters.HeaderToLabelFilter'
                }
            },
            'formatters': {
                'standard': {
                    'format': '%(levelname)-8s [%(asctime)s] [%(request_id)s] %(name)s: %(message)s'
                },
            },
            'handlers': {
                'console': {
                    'level': 'DEBUG',
                    'class': 'logging.StreamHandler',
                    'filters': ['request_id'],
                    'formatter': 'standard',
                },
            },
            'loggers': {
                'log_labeler.middleware': {
                    'handlers': ['console'],
                    'level': 'DEBUG',
                    'propagate': False,
                },
                {
                'gunicorn.access': {
                    'handlers': ['console'],
                    'level': 'INFO',
                    'propagate': False,
                },
            }
        }
        ```
        
        You can then output log messages as usual:
        
        ```python
        import logging
        logger = logging.getLogger(__name__)
        logger.debug("Hello world!")
        ```
