POST request / validation of page reloading.

[MichaelCh]

Hello Geert!

I have question related to the POST request processing.
I am concerned about use case when user can send twice the same POST
request by reloading the page.

Could you provide me some hints how to validate it using rife,
Element's methods ?
Do I need to check submission context, etc ?

Best regards,
Michael Chudas.

Hi,

there are several ways of doing this.

You can for instance redirect after post by setting up a 'redirect'  
exit. This makes it intuitive to trigger the exit, and the redirection  
will happen automatically.

Another possibility is to simply use continuations and to remove the  
active continuations tree when you're doing processing. People that  
press back and re-submit will not have the continuation to resume  
anymore, and they will to started all over again at the beginning of  
the interaction with the form(s).

Hope this helps,

Geert
