Hi @martinhsv,

just my not-so-essential opinion, but the 2fb7eef commit has no effect, because in our last affected commit we remove the unnecessary spaces from begin of all cookie keys.

Instead of this new method, I think it would make more sense to modify the other trim method:

   559              while (!final_cookie_pair.empty() && isspace(final_cookie_pair.back())) {
   560                  final_cookie_pair.pop_back();
   561              }

by this:

   559              while (!final_cookie_pair.empty() && (isspace(final_cookie_pair.back()) || final_cookie_pair.back() == ';')) {
   560                  final_cookie_pair.pop_back();
   561              }

With this we can trim the cookie string like these:
Cookie: foo=bar; baz=foo // this works now
Cookie: foo=bar; baz=foo ; // this would be more useful
Cookie: foo=bar; baz=foo ; // this could gives back same
Cookie: foo=bar; baz=foo; // same here

What do you think?
