While i'm studying a line of code in magento vendor file I found this code

$resultRedirect->setPath('*/*/');

What does this '*/*/' means and where does this redirects.
I hope will get clarification.

If you need to know detail about the following code then read the following:

$resultRedirect->setPath('*/*/');

First * means current route and second * means current controller. Let me explain it in detail with example.

Suppose you are submitting any form to http://example.com/someroute/somecontroller/someaction. Then in this case if you are using $resultRedirect->setPath('*/*/'); then it will redirect you to current route and current controller like http://example.com/someroute/somecontroller/index. Index action is here because if you have not mentioned any action $resultRedirect->setPath('*/*/');.

Suppose you are submitting any form to http://example.com/someroute/somecontroller/someaction. Then in this case if you are using $resultRedirect->setPath('*/*/test'); then it will redirect you to current route and current controller like http://example.com/someroute/somecontroller/test. Test action is here because if you have not mentioned any action $resultRedirect->setPath('*/*/test');.

Summary: First * for route, second * for controller and third for action.

It is used to redirect current route, current controller's index action.

Let say if you are currently browsing

checkout/index/customaction

if you are using this code in custom action controller, then it will redirect you to checkout/index/index
So in this case

checkout/index/index = '*/*/' OR '*/*/Index' (both are same);

here

First * denotes current route, in our example its checkout

Second * denotes controller, in our example its Index

Third * denotes action (if available otherwise Index by default)

if you use

'*/*/test'

Then in our example it will redirect you to checkout/index/test.

'*/*/*' means current action

Also we can say that '*/*' will redirect you to the current module's index controller

I hope you got idea on it.

 $resultRedirect->setPath('*/*/');

This will redirect you to the current module's index controller. For example you are on customer/account/create controller then If I write this line of code in controller it'll take you to customer/account/index controller.
