 ```
 `w` is the response of the request and cookie is a struct. Let's see what it looks like:
 ```Go
-	type Cookie struct {
-	    Name       string
-	    Value      string
-	    Path       string
-	    Domain     string
-	    Expires    time.Time
-	    RawExpires string
-	
-	// MaxAge=0 means no 'Max-Age' attribute specified.
-	// MaxAge<0 means delete cookie now, equivalently 'Max-Age: 0'
-	// MaxAge>0 means Max-Age attribute present and given in seconds
-	    MaxAge   int
-	    Secure   bool
-	    HttpOnly bool
-	    Raw      string
-	    Unparsed []string // Raw text of unparsed attribute-value pairs
-	}
+type Cookie struct {
+    Name  string
+    Value string
+    Path       string    // optional
+    Domain     string    // optional
+    Expires    time.Time // optional
+    RawExpires string    // for reading cookies only
+
+    // MaxAge=0 means no 'Max-Age' attribute specified.
+    // MaxAge<0 means delete cookie now, equivalently 'Max-Age: 0'
+    // MaxAge>0 means Max-Age attribute present and given in seconds
+    MaxAge   int
+    Secure   bool

+    SameSite SameSite
+    Raw      string
+    Unparsed []string // Raw text of unparsed attribute-value pairs
+}
 ```
 Here is an example of setting a cookie:
 
 ```Go
-	expiration := time.Now().Add(365 * 24 * time.Hour)
-	cookie := http.Cookie{Name: "username", Value: "astaxie", Expires: expiration}
-	http.SetCookie(w, &cookie)
+expiration := time.Now().Add(365 * 24 * time.Hour)
+cookie := http.Cookie{Name: "username", Value: "astaxie", Expires: expiration}
+http.SetCookie(w, &cookie)
 ```
 
 ## Fetch cookies in Go
 
 The above example shows how to set a cookie. Now let's see how to get a cookie that has been set:
 ```Go
-	cookie, _ := r.Cookie("username")
-	fmt.Fprint(w, cookie)
+cookie, _ := r.Cookie("username")
+fmt.Fprint(w, cookie)
 ```
 Here is another way to get a cookie:
 ```Go
-	for _, cookie := range r.Cookies() {
-	    fmt.Fprint(w, cookie.Name)
-	}
+for _, cookie := range r.Cookies() {
+    fmt.Fprint(w, cookie.Name)
+}
 ```
 As you can see, it's very convenient to get cookies from requests.
