[jira] Commented: (TAPESTRY-1836) Redirect after post causes issues
with maintaining client side persistence and forces use of session
[ https://issues.apache.org/jira/browse/TAPESTRY-1836?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12535886 ]
Kristian Marinkovic commented on TAPESTRY-1836:
-----------------------------------------------
i think everything you need is to save the serialized data from the From
into an annotated property with @Persist("flash"). The value of the property
will only stay in the session between the two request and will be cleared
afterwards.
the load balancer will have to have sticky session enabled so the second
request (redirect) reaches the same T5 instance.

> We have a lot of pages that serialize objects into the form (gzip + base 64). This is necessary because we want to absolutely avoid using the session (clustering concerns and multiple-browsers with same session concerns). In T5, a form post results in a redirect. So if serialized state is present in the form, the redirect will necessarily cause that to be lost (the URL with its 256 character limitation is not an option to pass the state through). Thus we are forced to hold the state in session. This leads to major problems when the user has multiple browsers open into the same session (which they always do given the nature of our application).
> An option is required to disable the redirect after form post.
