setMaxAge
Sets @cookie's max age to @max_age.
If @max_age is -1, the cookie is a session cookie, and will expire at the end of the client's session. Otherwise, it is the number of seconds until the cookie expires. You can use the constants %SOUP_COOKIE_MAX_AGE_ONE_HOUR, %SOUP_COOKIE_MAX_AGE_ONE_DAY, %SOUP_COOKIE_MAX_AGE_ONE_WEEK and %SOUP_COOKIE_MAX_AGE_ONE_YEAR (or multiples thereof) to calculate this value. (A value of 0 indicates that the cookie should be considered already-expired.)
This sets the same property as method@Cookie.set_expires.
