A computer-readable medium stores computer-readable instructions that control a communication on a communication apparatus that obtains a content summary information having at least content location information from a server. The instructions cause the communication apparatus to perform steps. The steps include receiving a delivery source information inputted through a user operation, determining whether the delivery source information includes a predetermined character string. Content summary information corresponding to the inputted delivery source information is obtained when the determining step determines that the predetermined character string is not included in the delivery source information. Content summary information corresponding to a predetermined alternative delivery source information is obtained when the determining step determines that the predetermined character string is included in the delivery source information.
