Method for sharing a Web application between several computing terminals linked to a communication network, said Web application being executed by a Web browser in a first computing terminal, during a first session initiated by a first user, the method being characterized in that: - in the first terminal, further to a prior determination of a set of terminals (U2, U3) with which to share said Web application, an application sharing request is dispatched destined for a first server on the network, said application sharing request including the launch Web address of said Web application and identification information identifying the first user and relating to said first session; - in response to the receipt of said sharing request in the first server, a predetermined computing device on the network launches a second execution session of said Web application by using said session identification information of the first user and said launch Web address, said second session taking as initial state the current state of execution of the first session; - in the predetermined computing device, a data stream of Virtual Network Computing type is created, this stream corresponding to the display data of the second execution session of said Web application, and then converted into a data stream directly readable by a Web browser, termed Web data stream; and, - said Web data stream is transmitted to each of the terminals of said set of determined terminals, in which said predetermined computing device is a virtual machine (VMi), the launching of a second execution session of said Web application in said predetermined computing device being preceded by: - the dispatching by the first server of a virtual machine activation request destined for a second server on the network, said activation request containing the launch Web address of said Web application and said session identification information of the first user; - in response to the receipt of said virtual machine activation request by the second server, activation of a virtual machine (VMi). - in the first terminal, further to a prior determination of a set of terminals (U2, U3) with which to share said Web application, an application sharing request is dispatched destined for a first server on the network, said application sharing request including the launch Web address of said Web application and identification information identifying the first user and relating to said first session; - in response to the receipt of said sharing request in the first server, a predetermined computing device on the network launches a second execution session of said Web application by using said session identification information of the first user and said launch Web address, said second session taking as initial state the current state of execution of the first session; - in the predetermined computing device, a data stream of Virtual Network Computing type is created, this stream corresponding to the display data of the second execution session of said Web application, and then converted into a data stream directly readable by a Web browser, termed Web data stream; and, - said Web data stream is transmitted to each of the terminals of said set of determined terminals, in which said predetermined computing device is a virtual machine (VMi), the launching of a second execution session of said Web application in said predetermined computing device being preceded by: - the dispatching by the first server of a virtual machine activation request destined for a second server on the network, said activation request containing the launch Web address of said Web application and said session identification information of the first user; - in response to the receipt of said virtual machine activation request by the second server, activation of a virtual machine (VMi). - the dispatching by the first server of a virtual machine activation request destined for a second server on the network, said activation request containing the launch Web address of said Web application and said session identification information of the first user; - in response to the receipt of said virtual machine activation request by the second server, activation of a virtual machine (VMi).
