A computer program product for content delivery by simulating user web page visits embodied in a non-transitory, computer readable medium, the computer readable medium having stored thereon a sequence of instructions which, when executed by a processor causes the processor to execute a process, the process comprising:
- using a content server, that comprises one or more first processors and one or more first memories, to perform first actions including:
- receiving, from a client device, a request that includes one or more constraints and is for data corresponding to user sessions characterizing web page visits that satisfy at least one of the one or more constraints;
- and
- sending the request to a simulation server;
- using the simulation server, that comprises one or more second processors and one or more second memories, to perform second actions including:
- transmitting, to a visit database, a query for session records that include a timestamp within a predefined time period;
- receiving, as a result of the query and from the visit database, a set of session records, each session record of the set of session records comprising a set of record attributes, the set of record attributes identifying a user ID, a URL, and a first timestamp, wherein the first timestamp indicates a time of a visit to the URL by a user device associated with the user ID;
- generating, for each session record of the set of session records, a simulated HTTP call of a set of simulated HTTP calls or the session record, wherein the simulated HTTP call includes one or more properties, wherein a first property of the one or more properties corresponds to a record attribute of the set of record attributes included in the session record, and wherein a second property of the one or more properties includes a second timestamp that is different than the first timestamp;
- sending, to a visit server, the set of simulated HTTP calls;
- using the visit server, that comprises one or more third processors and one or more third memories, to perform third actions including:
- receiving the set of simulated HTTP calls;
- for each simulated HTTP call of the set of simulated HTTP calls:
- identifying, using the first property of the simulated HTTP call and from amongst the set of session records, a session record that corresponds to the simulated HTTP call, as an identified session record of a set of identified session records;
- and
- updating the identified session record to include one or more updated record attributes that represent a simulated session associated with the second timestamp and corresponding to the simulated HTTP call to produce an updated session record of a set of updated session records;
- sending the set of updated session records to the content server;
- further using the content server to perform fourth actions including:
- identifying a subset of the set of updated session records, wherein, for each updated session record in the subset, a constraint-processing condition is satisfied based on the set of record attributes in the updated session record;
- generating a response communication that includes, for each updated session record in the subset, data from the updated session record;
- and
- transmitting, to the client device, the response communication.
