Disable the command system



Hello everyone

I have the project to put maxima on my page in order to my students use 
it from a web interface. But, I need to disable the command system of 
maxima, which gives access to execute commands in the system. I have not 
found documentation on the subject.

Any suggestions?

Thanks
