Returns a pointer to the AutoConnectAux object of the custom Web page that caused the request to the page.< br >
AutoConnect identifies the URI (ie. the referrer URI) that caused the request each time from the client occurs and will save the URI If the request source is a custom Web page of AutoConnectAux. The < strong > where< / strong > function returns a pointer of AutoConnectAux which is a URI of a least recent request from the custom Web page.< br >
This function is provided to access the fields (ie. the AutoConnectElements) with a custom Web page handler of a page and is available only for request source that is the custom Web pages. It is invalid for HTTP requests from individual pages registered with the < strong > on< / strong > handler of ESP8266WebServer/WebServer for ESP32. In other words, this function only returns the AutoConnecAux page which is a least recently displayed.
