identifying, by the content server, a matching identifier included in both the first plurality of candidate identifiers and the second plurality of candidate identifiers; assigning, by the content server, a first weight to the matching identifier based on the matching identifier being included in both the first plurality of candidate identifiers and the second plurality of candidate identifiers, and based on a pre-cached media file corresponding to the matching identifier satisfying additional content selection criteria; selecting, by the content server, based on the first network type satisfying the network type condition, from the second plurality of candidate identifiers, the matching identifier based on the first weight; and transmitting, by the content server to the client device, a response comprising the matching identifier to cause the client device to display a media file identified by the matching identifier. ### Claim 9 (depends on 8) The method of claim 8, further comprising: receiving, by the content server from the client device while the client device is connected to a second network different from the first network, at a first time prior to receiving the request for content, an initial request for an initial media file; and transmitting, by the content server to the client device responsive to receiving the initial request for the initial media file, the initial media file to be stored as a pre-cached media file. ### Claim 10 (depends on 9) The method of claim 9, wherein the first network is a cellular network and the second network is a Wi-Fi network. ### Claim 11 (depends on 8) The method of claim 8, wherein the response further comprises additional display instructions that specify a frame or window in which the media file identified by the matching identifier is to be shown, and instructions to transmit media playback statistics to a measurement server. ### Claim 12 (depends on 11) The method of claim 11, wherein the instructions to transmit the media playback statistics to the measurement server comprises instructions to transmit information identifying at least one of: a number of times the media file was displayed, a device type on which the media file was displayed, or a playback time during display of the media file at which a remainder of the display of the media file was skipped. ### Claim 13 (depends on 8) The method of claim 8, wherein selecting, by the content server, the matching identifier further comprises: assigning, by the content server, respective selection weight points to each of a plurality of monetary agreements each associated with media files, at least one monetary agreement associated with the media file identified by the matching identifier, including assigning at least one selection weight point to the monetary agreement associated with the media file identified by the matching identifier based on the media file identified by the matching identifier being pre-cached at the client device;
