The closest thing that I could find in the help file was something about "contains=@NoSpell" but I do not really understand it. How would I go about setting it up, or at least, where could I read more about it?

:help syntax
:help :syn-match

If you are just editing a plaintext file with no existing syntax highlighting, it is very easy. Assuming you have "syntax on" in your .vimrc somewhere, just do something like this:

:syntax match NoSpellURL 'http://\S*' contains=@NoSpell

You can type this directly, put it in a mapping or command, or put this in a file with pretty much any name you want, in ~/.vim/syntax, and set the syntax to the chosen name to activate it. E.g. if you name the file ~/.vim/txtspell.vim you can do :set syntax=txtspell to apply the rule.

It gets somewhat more complicated if you have an existing syntax you want to enhance with this rule but is still quite possible. The "after directory" is useful for this, i.e. ~/.vim/after/syntax.
