1. A method for correlating a front-end query transmitted in a computer network environment with a plurality of network-based back-end transactions relating to generation of a response to the front-end query, the method comprising: identifying network-based back-end transactions occurring between transmission of the front-end query and receipt of the response to the front-end query; analyzing each identified network-based back-end transaction to determine whether the network-based back-end transaction has a correlation with the front-end query, wherein the analyzing includes detecting and collecting at least one of a back-end query and a back-end reply of each identified network-based back-end transaction and wherein the analyzing comprises at least one of computing a timing proximity score that is a distance in standard-deviation units and determining a correlation between the front-end query and the identified network-based back-end transaction based on a byte size ratio; and associating, in a database, the front-end query with each identified network-based back-end transaction determined to have a correlation with the front-end query.
