any features you described are on the server side (as to your post title)

If you think otherwise, you'll have to prove it to be taken seriously :)
You are asking about the server
I am not. Again, please refer to the first three words in the body of post. In general, I urge you to read posts before you respond to them.

If you do not have an argument to make or anything of value to add, please stop replying to my comments or I will ignore them going forward.
