C has the following statement
printf ("Set-Cookie:username =% s; path=/\ r\ n", username);
can be set successfully and can be read at the front end.
but if I want to set two values, I try the following methods:
printf ("Set-Cookie:username =% s; password =% s; path=/\ r\ n", username, password);
or
printf ("Set-Cookie:username =% s; path=/\ r\ n", username);
printf ("Set-Cookie:password =% s; path=/\ r\ n", password);

neither of these methods works, so how to set it
