Definitions
- the invention lies in the field of the display on a display device of a local terminal of a graphic object generated by a remote server. More specifically, the invention applies to a local terminal and a remote server implementing a remote desktop protocol. It applies in particular to the remote desktop protocol known as RDP, for the English Remote Desktop Protocol.
- RDP remote desktop protocol
- RAC Remote Desktop Protocol
- ICA English for Independent Computing Architecture
- Such computer systems transmit to the remote server, via a network connection, pressure actions performed on a keyboard and clicks made on a mouse of the local terminal, while ensuring the refresh of the display device. of the local terminal, by transmitting to the local terminal the updates of a display generated by the remote server. Also, the local terminal receives only display updates generated by the remote server.
- Remote desktop protocols such as RDP, distinguish a desktop connection (Remote Desktop English) and a remote application type (RemoteApp).
- a desktop connection has a display of a desktop generated by the remote server in a so-called local or local desktop window displayed on a display device of the local terminal.

- an office may include a "Start" menu, a taskbar, a notification area, and one or more windows corresponding to one or more open applications on the remote server.
- a desktop connection displays the entire desktop generated by the remote server in the local window.
- a disadvantage of a desktop connection is that the desktop is predetermined in size before the establishment of said connection and remains fixed in size for the duration of said connection: a user can not resize.
- the local window can be moved or narrowed. In the case where it is narrowed, part of the office is hidden; the visible part can be adapted by using scrollbars located on the sides of the window.
- a remote application type connection has a display generated by an application running on the remote server in one or more windows, called local or local application type, displayed on a display device of the local terminal. Also, instead of presenting the entire desktop of the remote server, only the display generated by the application running on the remote server is presented in the local windows type application. Local application windows are resizable, can be moved on a single screen of a display device, or dropped between multiple screens of a display device and have their own entries on the taskbar of the desktop. local terminal. Also, an application-type connection gives the user the feeling, which is false, that the application, whose display is displayed on the local windows of the application type, is an application running on the local terminal.
- a disadvantage of remote desktop protocols is that it is not possible to establish a connection, respectively, of a type, desktop or application, between a local terminal and a remote server, for access the resources that the latter offers, respectively of the other type, application or office.
- An object of the invention is in particular to overcome all or part of the aforementioned drawbacks.

Also, the method P allows a user of the local terminal to display, in local windows of the application type, both a display of a desktop generated by a remote server and a display generated by an application running on said remote server, which solves the purpose of the invention previously exposed.
- the method P may also comprise, prior to the detection step, a step of presentation to the local terminal, after an optional step of connecting the local terminal to the proxy gateway, a list of remote server choices to the terminal local
- the list of remote servers to the local terminal may depend on the user of the local terminal, its entitlement levels, and so on.
- the list of remote servers may include at least two remote server choices for which the remote connection types are distinct.
- the proxy gateway can be configured to pool several connections within the same primary connection or, on the contrary, separate them.
- the Load Balance Info field of the RDP protocol can be used by the proxy gateway for this purpose, two RDP connections having two fields of different values being two separate connections.
- the method according to the invention makes it possible to resize a local window of the office type.
- the method according to the invention may comprise, while a remote application-type primary session displays an application window presenting an office of a remote server: a step of detecting commands from said local terminal and relating to the application-type local window, said commands corresponding to a resizing of the application-type window,
- Office-type windows converted to an application-type window virtually use a desktop that is the size of all the combined surfaces of physical screens of the local client. This can be disproportionately large compared to the size of the area actually occupied by the application type window.
- the local client has two 1920x1080 Full HD displays, and if the server has 800x600 screen, the server desktop is very small compared to the local client desktop.
- the gateway sees the display orders of a RemoteApp application session as drawing orders for the windows of the application on all the screens of the user station.
- the order geometry produces a rectangular record encompassing all the screens of the user station. Windows may appear, if they are not in full-screen mode, lost in the middle of a large black rectangle.
- the method according to the invention may comprise a step of determining a rectangle of minimum width and height which is calculated so as to encompass the windows throughout the duration of the session.
- the determined rectangle Only the contents of the rectangle determined rectangle can be saved in a video so as to minimize unnecessary space around the windows. In the case where the application has only one window, the determined rectangle exactly matches the surface of the application window.
- the method may include real-time determination of a rectangle to encompass all windows visible at the time of calculation. Real-time visualization can therefore vary in size during the session.
