Hi. My solution to this was to create a new file, goodbye.pug.
extends layout
block content
form(action="/goodbye", method="post")
label Goodbye!
In app.js, the goodbye code:
app.get("/goodbye", (req, res) => {
res.cookie("username", req.body.username);
res.redirect("/hello");
});
When I tested this, nothing was different from before.

For checking if it works go to homepage, enter your name in form-field and press submit, you have to see welcome content with your name. After this click button 'Good Bye' and app will redirect you to '/hello' page with empty form for filling it.

12,326 PointsHey! Almost right, but i missed one more thing. Replace in app.js get method to post. And you dont have to clear all cookies in dev tools manually, button goodbye should delete username from cookie. When you entered your name and submit it - appeared Welcome message with your name. This name exists in cookie-file. When you pressed goodbye button - username deletes from cookie and redirect you to '/hello' page.

12,326 PointsHello, Sean!
- In goodbye.pug you have to add button for action, not just label. Replace 'label' to 'button'.
- In app.js you have to clear cookie before try to redirect to '/hello'. In your code you sending it. Replace
res.cookie("username", req.body.username)tores.clearCookie("username")and it will work

33,235 PointsHi Avi! Thanks for your help!
I've changed goodbye.pug. Is this what it should be?
extends layout
block content
form(action="/goodbye", method="post")
button Goodbye!
And app.js:
app.get("/goodbye", (req, res) => {
res.clearCookie("username");
res.redirect("/hello");
});
I ran localhost:3000/goodbye, entered my name, clicked the Submit button and a cookie appeared in Dev Tools. The welcome message appeared and I clicked Clear All in Dev Tools to delete the cookie.
Is that right?

I changed get to post. I ran node app.js. I opened localhost:3000/goodbye but the output was Cannot GET /goodbye. I checked the console but it contained a 404 (not found) error message.
