Redirect to a specific url?

[jamesli2021]

Read thru Echo documentation and I don't have an idea how to write a route when I'm saving a post in .../post?id=234, it will redirect back to the same url .../post?id=234 and a flash message.

c.redirect() seem not an option?

Could you specify why Redirect() will not do? You could add flash message or message identifier in that url you are redirecting to and use it to render that message on GET request.

I did use url as a way to flash message and it will keep flashing every time user reload the same page can be confusing.

Using sessionstorage could solve the problem with url but this require JavaScript.

Using cookie to render flash message seem workable.

Are there more options which I could achieve with Go stdlb and missing in Echo?

I feel c.RedirectWithData() can be handy for a scenario when user have failed login or signup and email/username will retain.

redirectWithData == c.Redirec(code, path, data)
redirectWithoutData == c.Redirect(code, paht, nil)

redirectWithData == c.Redirec(code, path, data) redirectWithoutData == c.Redirect(code, paht, nil)

Assume you are proposing an API that includes the last parameter, this will cause break changes.
