translate the remote desktop drawing command into a graphics drawing command compatible with the transcoding server, and

update a portion of an image representing the entire remote desktop and coordinates based on the graphics drawing command, and

wherein the HTTP handler is configured to:

generate an image file based on the updated portion of the image,

obtain drawing coordinates based on the coordinates in response to the drawing request, wherein the web browser drawing update comprises the image file and the drawing coordinates, and

provide the web browser drawing update to the web browser in real time including placing the drawing coordinates into a cookie to be provided to the web browser.

2. The non-transitory machine-readable storage medium of claim 1 , wherein the user input request comprises at least one of a mouse event, a keyboard event, and a touch event.

3. The non-transitory machine-readable storage medium of claim 1 , wherein the session control command relates to establishing or controlling a connection between the remote desktop client and the remote desktop server and comprises at least one of: a command for starting the remote desktop session, a command for stopping the remote desktop session, a credential, a setting, a preference, and a command for passing at least one of a credential, a setting, and a preference.

4. The non-transitory machine-readable storage medium of claim 1 , wherein the graphics drawing command is a Java graphics drawing command, wherein the transcoding server is a Java transcoding server.

5. The non-transitory machine-readable storage medium of claim 1 , wherein the remote desktop client adapter is configured to place the image and the coordinates into a drawing commands queue,

wherein the machine-readable storage medium further comprises a long polling handler,

wherein the long polling handler is configured to receive the drawing request from the web browser utilizing HTTP, to forward the drawing request to the HTTP handler if coordinates for an image are pending in the drawing commands queue, to place the drawing request into a drawing requests queue if coordinates for an image are not pending in the drawing commands, and

wherein the drawing commands queue is configured to send a notification to the drawing requests queue if the drawing commands queue receives a new drawing command comprising an image and coordinates for an image.

6. The non-transitory machine-readable storage medium of claim 1 , further comprising a drawing requests queue configured to forward the drawing request to the HTTP handler in response to a notification from a drawing commands queue that a drawing command is pending for the web browser.

7. The non-transitory machine-readable storage medium of claim 1 , wherein the HTTP handler is configured to place the drawing coordinates into a section of an HTTP header, wherein the HTTP handler is configured to facilitate providing the image file and the drawing coordinates together to the web browser in a single HTTP transmission response for drawing a display image at the web browser, wherein the display image represents the updated portion of the image representing the entire remote desktop.

8. The non-transitory machine-readable storage medium of claim 1 , wherein the HTTP handler is configured to provide script client code compatible with the web browser to the web browser if the connection request from the web browser comprises a request to connect to the remote machine.

9. A method for facilitating accessing and controlling a remote desktop of a remote machine, the method comprising:

receiving, at a transcoding server, a connection request from a web browser utilizing hypertext transfer protocol (HTTP),

translating, at the transcoding server, the connection request into a session control command compatible with a remote desktop display protocol;

providing the session control command to a remote desktop client of the transcoding server for providing the session control command to a remote desktop server of the remote machine and for establishing, controlling or terminating a remote desktop session with the remote desktop server;

receiving, at the transcoding server, a user input request from the web browser utilizing HTTP,

translating, at the transcoding server, the user input request into a remote desktop input command compatible with the remote desktop display protocol;

providing the remote desktop input command to the remote desktop client for providing the remote desktop input command to the remote desktop server;

receiving, at the transcoding server, a remote desktop drawing command from the remote desktop server via the remote desktop client in response to the remote desktop input command, wherein the remote desktop drawing command is compatible with the remote desktop display protocol, and wherein the remote desktop drawing command represents a portion of an entire image of the remote desktop;

translating, at the transcoding server, the remote desktop drawing command into a graphics drawing command compatible with the transcoding server;

updating, at the transcoding server, a portion of an image and coordinates based on the graphics drawing command;

generating, at the transcoding server, an image file based on the updated portion of the image;

obtaining drawing coordinates based on the coordinates; and

providing a web browser drawing update to the web browser in real time in response to a drawing request from the web browser including placing the drawing coordinates into a cookie to be provided to the web browser, wherein the web browser drawing update comprises the image file and the drawing coordinates, and wherein the web browser drawing update is compatible with the web browser.

10. The method of claim 9 , wherein the user input request comprises at least one of a mouse event, a keyboard event, and a touch event.

11. The method of claim 9 , wherein the session control command comprises at least one of: a command for starting the remote desktop session, a command for stopping the remote desktop session, a credential, a setting, a preference, and a command for passing at least one of a credential, a setting, and a preference.

12. The method of claim 9 , wherein the graphics drawing command is a Java graphics drawing command, wherein the transcoding server is a Java transcoding server.

13. The method of claim 9 , wherein the updating a portion of an image and coordinates comprises storing the portion of the image and the coordinates into a drawing commands queue,

wherein the method further comprises:

receiving the drawing request from the web browser utilizing HTTP;

forwarding the drawing request to an HTTP handler if coordinates for an image are pending in the drawing commands queue;

placing the drawing request into a drawing requests queue if coordinates for an image are not pending in the drawing commands, and

sending a notification to the drawing requests queue if the drawing commands queue receives a new drawing command comprising an image and coordinates for an image.

14. The method of claim 9 , further comprising forwarding the drawing request to an HTTP handler in response to a notification from a drawing commands queue that a drawing command is pending for the web browser.

15. The method of claim 9 , further comprising placing the drawing coordinates into a section of an HTTP header, wherein the providing the web browser drawing update comprises providing the image file and the drawing coordinates together to the web browser in a single HTTP transmission response for drawing a display image at the web browser, wherein the display image represents the updated portion of the image representing the entire remote desktop.

16. The method of claim 9 , further comprising providing script client code compatible with the web browser, to the web browser, if the connection request from the web browser comprises a request to connect to the remote machine.
