I get things working with help by styfle, and now I have this working: olympiccode.xyz/download/plugin/hgjg/ff olympiccode.xyz/download/plugin/anything/here
Now I want to redirect by the input on the URL, for example, if a person used this URL: olympiccode.xyz/download/plugin/anything/here How I can redirect him to olympiccode.xyz/download/files/pl/anything-here.jar (the anything-here.jar is changed by what the person put in the URL)
//Old question
I don't know the name of this things so I used "Custom automatic URL", what I mean is some links like those:
https://crafatar.com/capes/jeb_
https://crafatar.com/capes/Notch
