Abstract: A method includes receiving, at a proxy server, a first request for advertising content from a computing device. The first request is responsive to display of an e-mail directed to an e-mail address of a user and received by the computing device. The first request includes an identifier uniquely identifying the user and the e-mail. An application of the computing device associated with presentation of the advertising content does not support local storage of cookies. The method includes generating the cookie at the proxy server in response to determining that a cookie managed by the proxy server and associated with the identifier is unavailable. The method also includes sending, from the proxy server to an advertising server, a second request that includes at least a portion of the cookie. The method also includes receiving the advertising content from the advertising server and sending the advertising content to the computing device.

Abstract: A method includes receiving, at a proxy server, a first request for content from a computing device. The first request includes an identifier that uniquely identifies a user and an e-mail. The method also includes, in response to receiving the first request, sending a second request to a first server. The second request includes at least a portion of a cookie associated with the identifier. The method also includes receiving the content at the proxy server from the first server and sending the content from the proxy server to the computing device. The method further includes, subsequent to receiving the first request, determining, at the proxy server, information regarding resolution of dynamic links associated with the content. The information includes a count of a number of times that the content has been accessed outside a time to live (TTL) of the cookie by web browsers or by e-mail clients.

Abstract: A method includes receiving, at a proxy server, a first request for advertising content from a computing device, where the first request includes an identifier and where the first request is associated with an e-mail received by the computing device. The method also includes determining whether state information associated with the identifier is available. The method further includes, in response to determining that the state information associated with the identifier is unavailable, generating the state information associated with the identifier at the proxy server. The method also includes sending a second request for the advertising content from the proxy server to an advertising server, where the second request includes at least a portion of the state information associated with the identifier. The method also includes receiving the advertising content from the advertising server. The method further includes sending the advertising content to the computing device.
