If this new URL is found in urlpatterns, then an HTTP-redirect is returned to this new URL; otherwise the initial URL is processed as usual. This behavior can be customized by subclassing CommonMiddleware and overriding the response_redirect_class attribute. - ETags: If the USE_ETAGS setting is set, ETags will be calculated from the entire page content and Not Modified responses will be returned appropriately. USE_ETAGS is deprecated in favor of ConditionalGetMiddleware. cCsõd|jkrKx9tjD]+}|j|jdƒrtdƒ‚qqWn|jƒ}tjos|os|jdƒ }|rd|j|fnd}|j |ƒr¶|j |ƒ}n |j ƒ}|sÚ||j ƒkrñ||7}|j |ƒSdS(s‚ Check for denied User-Agents and rewrite the URL based on settings.APPEND_SLASH and settings.PREPEND_WWW tHTTP_USER_AGENTsForbidden user agentswww.s %s://www.%stN( tMETARtDISALLOWED_USER_AGENTStsearchRtget_hostt PREPEND_WWWt startswithtschemetshould_redirect_with_slashtget_full_path_with_slasht get_full_pathtresponse_redirect_class(tselftrequesttuser_agent_regexthostt must_prependt redirect_urltpath((sB/usr/local/lib/python2.7/dist-packages/django/middleware/common.pytprocess_request-s   cCsYtjrU|jjdƒ rUt|ddƒ}t|j|ƒ oTtd|j|ƒStS(s˜ Return True if settings.APPEND_SLASH is True and appending a slash to the request path turns an invalid path into a valid one. t/turlconfs%s/N(Rt APPEND_SLASHt path_infotendswithtgetattrtNoneRtFalse(RRR$((sB/usr/local/lib/python2.7/dist-packages/django/middleware/common.pyRIs cCsh|jdtƒ}t|ƒ}tjrd|jdkrdtdi|jd6|jƒ|d6ƒ‚n|S( sÀ Return the full path of the request with a trailing slash appended.
