A method for identifying a resource leak on a web server in a production environment, the method comprising: receiving a first hyper-text protocol (HTTP) request message transmitted by a client, the first request message including an identifier of an information component stored on the first web server, wherein the first web server is a production web server, and characterised in that a multiplier: receives a forwarded first HTTP request message from the first web server or from a plug-in to the first web server; generates multiple additional HTTP request messages for the information component by copying the first request message, each of the additional request messages including the identifier of the information component; transmits the additional request messages to a second web server, wherein the second web server is a test server that also hosts said information component, thereby amplifying the number of request messages for the information component in order to increase the size of any resource leak associated with the information component and so make the resource leak easier to detect and diagnose without disturbing the production environment; and analyzes the effect of the additional request messages upon the second web server. receiving a first hyper-text protocol (HTTP) request message transmitted by a client, the first request message including an identifier of an information component stored on the first web server, wherein the first web server is a production web server, and characterised in that a multiplier: receives a forwarded first HTTP request message from the first web server or from a plug-in to the first web server; generates multiple additional HTTP request messages for the information component by copying the first request message, each of the additional request messages including the identifier of the information component; transmits the additional request messages to a second web server, wherein the second web server is a test server that also hosts said information component, thereby amplifying the number of request messages for the information component in order to increase the size of any resource leak associated with the information component and so make the resource leak easier to detect and diagnose without disturbing the production environment; and analyzes the effect of the additional request messages upon the second web server. receives a forwarded first HTTP request message from the first web server or from a plug-in to the first web server; generates multiple additional HTTP request messages for the information component by copying the first request message, each of the additional request messages including the identifier of the information component; transmits the additional request messages to a second web server, wherein the second web server is a test server that also hosts said information component, thereby amplifying the number of request messages for the information component in order to increase the size of any resource leak associated with the information component and so make the resource leak easier to detect and diagnose without disturbing the production environment; and analyzes the effect of the additional request messages upon the second web server.
