WHEN we should not transfer data through URL || @PathVariable || Let’s set up the Email Form

As discussed, we are going to implement the spring mail API in our project. So to get started, we must develop an email screen first.

In this video, we are going to create the UI for the email form.

I am also going to explain, How to transfer data between different screens.

In episode no 4, We learned how to use @RequestParam.

Well, The @RequestParam will help, when you are receiving data through the query string. But imagine a URL "myUrl/{DynamicData1}/{DynamicData2}.

How can we handle this kind of URL which contains dynamic data?

Well, Today I will also give you an Introduction to @PathVariable. The @PathVariable will help you handle the URL containing dynamic data in it.

Last but not least, I will also explain why it's not good to send data using URL. I will walk you through some scenarios, where sending data through URL can be a headache. (WHEN should we not transfer data through URL)

Once I cover all of this, I will talk about the session and cookies in the next video of my spring MVC intermediate series.
