     Mobile communication device end-users constantly face a particular problem when using a local WiFi connection with a mobile communication device. Many times, whether on an airplane, in a hotel room, or in another facility with a local WiFi connection, a user attempts to run an application on a mobile communication device and the application times-out. Upon inspection, the end-user determines that the signal strength is good and there is a connection to a local WiFi connection. Some end-users will try to start a browser of the mobile communication device to determine if there is something that needs to be agreed to or a login. Other end-users will be bewildered, and frustrated that they cannot access an application on the mobile communication device.

At block  4020 , the mobile application attempts to access a website, joingo.com, over a network through a WiFi connection at a facility. If accessing the website fails, at block  4030 , an inquiry is made if a cache is available. If the cache is available, then at block  4040 , the mobile application operates in an offline mode. If the cache is not available, then at block  6050  there is not Internet connectivity. However, if at block  4020  the access to joingo.com is successful, then at block  4060  a GET request is sent for joingo.com/ping. If the GET request is successful, then at  4070  the operation is done. However, if the GET request is redirected, then at block  4080  a login error is generated for the mobile application to have the end-user of the mobile communication device try to LOGIN. At block  4090 , a browser of the mobile communication device is launched and the connection to the link is made over the network through the WiFi connection of the facility.
