示例1: cachedUrl
/**
* This function is very useful to use with clients like PhoneGap which can
* intercept URLs and load whatever locally cached files are stored in their bundle.
* The urls for these files will be relative to the cache base url.
* (See Q_Uri::cacheBaseUrl function).
* In this case, the client is supposed to send the timestamp of when the
* cache it is using was generated.
* This function checks the current contents of the Q/config/Q/urls.php file,
* generated by scripts/Q/urls.php script.
* If the url's timestamp there is newer than the Q_Request::cacheTimestamp()
* (which the client can set by setting the 'Q_ct' field in the querystring)
* then that means the server has a newer version of the file, so the passed
* $url is used instead.
* Otherwise, the url relative to cacheBaseUrl is used, making the client
* load the locally cached version.
