So I have a url imagine ...
The idea is for me to add a parameter or a variable to a url:
This parameter is written by the user when defining the url. The idea is then to use the parameter to define what will appear on the page.
What I do not understand is: how come by putting this address ...
It will look like the content that is already in:
where url are different ...
I do not want to redirect to another page I just want to use that parameter in a script later.
