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. cCs|jd}|durtjD] }||rtdq |}tjrC|rE|dsG| |r2| |}n| }| |j d||SdSdSdS)z Check for denied User-Agents and rewrite the URL based on settings.APPEND_SLASH and settings.PREPEND_WWW HTTP_USER_AGENTNzForbidden user agentzwww.z://www.)METAgetrDISALLOWED_USER_AGENTSsearchrget_host PREPEND_WWW startswithshould_redirect_with_slashget_full_path_with_slash get_full_pathresponse_redirect_classscheme)selfrequest user_agentuser_agent_regexhostpathrN/var/www/html/rh/venv/lib/python3.10/site-packages/django/middleware/common.pyprocess_request"s      z CommonMiddleware.process_requestcCsTtjr(|jds(t|dd}t|j|s(td|j|}|r(|j}t|ddSdS)z Return True if settings.APPEND_SLASH is True and appending a slash to the request path turns an invalid path into a valid one. /urlconfNz%s/should_append_slashTF)r APPEND_SLASH path_infoendswithgetattrrfunc)rrr"matchviewrrrr>s   z+CommonMiddleware.should_redirect_with_slashcCsD|jdd}t|}tjr |jdvr td|j||d|S)z Return the full path of the request with a trailing slash appended.
