I have installed Cloudbase's FreeRDP on my machine. Post installation, I start the FreeRDP server and connect to the web interface, provide the remote machine details, I am able to see the remote desktop on my browser. The whole of the remote desktop is displayed inside a Canvas tag. Whenever the mouse pointer changes in the remote machine(based on what you point it to, it changes to loading/resize/...pointers), the cursor property in the Canvas tag changes and hence the mouse pointer changes. But the tricky part is, the wsgate.js, mootools.js don't use the browser builtin mouse pointers but generates random numbers as url parts and fetches the mouse pointer from some location that is not available on the server. I am missing out on something. Need help in understanding how this works.
The Request URL http://localhost:8000/cur/00679488/8 is the url for the cursor, but in the server directory I dont find the 'cur' folder.
As an alternative, also open source and based on FreeRDP, you may have a look to Myrtille. I tried to simplify as most as possible the mouse (including the pointer) and keyboard events handling.
The main difference over FreeRDP-WebConnect is that Myrtille is written in C# (.NET) and the gateway is hosted on IIS.
Disclaimer: I made Myrtille.
