Hi Danish,

You could do that but then the URL would be misleading to the user. There's also the possibility that you'd have to write duplicate logic as your app gets bigger. It's much less of a headache if you just redirected the user's client to another route. Let me know if that doesn't makes sense.

Hi Mikis :) So if my understanding is correct. We use render to render and view a .pug file; on the other hand, we use redirect to transfer the control to a different route located within the same app.js file. Correct? :)

That's correct, Kenneth :)

Hi Mikis :) Thanks for answering :D My next question is if lets say the route has a GET method, the system will only allow any redirects to other routes with a GET method only and vice versa for the POST?

Sort of... but it's a bit more complicated than that. Ask this as a new question on the forum and tag me; when I get a chance, I'll answer it.

If you just want something to Google instead, try researching the 307 HTTP Status Code. Also, ExpressJS's redirect method has an optional first-parameter where you can specify a status-code.
