Abstract

A method and apparatus are provided for capturing and managing user-specific data, where the user-specific data contains information on the user'"'"'s interaction with the Net. The method generally involves using a proxy to capture or cause to capture the user-specific data and then storing the user-specific data. The user-specific data may be used to customize the contents of electronic information delivered to the particular user.

Claims

using a proxy, through which the one or more users send messages to addresses associated with a plurality of other servers on a network, to continuously generate records that indicate the servers to which each of the one or more users sends messages;

generating user-specific usage data based on the records;

causing the proxy to open a connection to a first server on the network;

streaming the user-specific usage data over the connection to the first server; and

storing the user-specific usage data at the first server.

2. The method of claim 1 further comprising the steps of:

causing the proxy to open a second connection to a second server on the network;

streaming the user-specific usage data over the connection to the second server; and

wherein the step of storing the user-specific usage data includes storing the user-specific usage data at the second server.

3. The method of claim 1 wherein the step of streaming the user-specific usage data over the connection to the first server includes sending the user-specific usage data to the first server in real-time as the records are generated.

4. The method of claim 1 wherein the step of streaming the user-specific usage data over the connection to the first server includes storing the user-specific usage data at the proxy and sending the user-specific usage data to the first server in batches.

5. The method of claim 1 further comprising the steps of:

causing the proxy to open a connection to a first server on the network;

downloading the user-specific usage data over the connection to the first server; and

wherein the step of storing the user-specific usage data includes storing the user-specific usage data at the first server.

6. The method of claim 5 further comprising the steps of:

causing the proxy to open a second connection to a second server on the network;

downloading the user-specific usage data over the connection to the second server; and

wherein the step of storing the user-specific usage data includes storing the user-specific usage data at the second server.

7. The method of claim 5 wherein the step of downloading the user-specific usage data over the connection to the first server includes causing the first server to retrieve in real-time from the proxy the user-specific usage data as the records are generated.

using a second proxy, through which a second set of one or more users send messages to addresses associated with the plurality of other servers on the network, to continuously generate records that indicate the addresses to which each user in the second set of the one or more users sends messages;

generating a second set of user-specific usage data based on the records;

causing the second proxy to open a second connection to a first server on the network;

streaming the second set of user-specific usage data over the second connection to the first server; and

storing the second set of user-specific usage data at the first server.
