Posting comments should use the POST-REDIRECT-GET pattern
---------------------------------------------------------
Key: MGNLCMNT-67
URL: http://jira.magnolia-cms.com/browse/MGNLCMNT-67
Project: Magnolia Commenting Module
Issue Type: Improvement
Security Level: Public
Affects Versions: 1.2.1
Reporter: Tobias Mattsson
Adding a comment is done using a POST request, as a response the page is
rendered with the new comment added.
If the user then tries to reload the page the browser will ask if the user
really wants to resubmit form data. If the user agrees then the comment is
added to the page again. If the user goes back using the back button he/she
will also get the warning when using the forward button to return to the page.
This also happens if the user navigates from the page with the comments and
then goes back.
The commenting component should return a redirect when it has added the comment
making the browser execute a GET request to see the page with the comment
added. The POST and redirect don't become part of the history so the user can
freely navigate back and forth and reload the page without the warning.
This should be trivial to implement using the model execution feature added in
4.4.
