if one is used to Mathematica (and Maple also), then trying sympy/python, will get at first confused by this. in sympy, assigning a value to symbol, does not change the value of expressions that contain that symbol. Here is a screen shot.
I am not sure now what to make of this and which is "better", but it is definitely something different from what I would expect CAS to do. Will see.
@C.E. @b3m2a1 @CarlLange and others with web dev experience. How to put a cloud object behind own website authentication and make sure that the cloud object's url won't escape or won't be accessible for others if it escapes.
@Kuba What is the function of the cloud object URL? Is it an API that you make POST requests to, or do you make GET requests to it, or what does it support?
If this is an API, then the usual solution is that the API endpoint (the URL in this case) requires for example a token to be sent along with the request. This token is then validated on the server.
For example: Your website can generate a token and incorporate this into the URL. It also stores the token to its database. When your cloud object receives the token, it sends it to an endpoint on your website to check that the token is valid. If the token is valid, it proceeds with the response.
