Re: [Springframework-developer] SWF - Creating HTTP sessions - Feedback needed

[Alef A. <al...@jt...>]

It's what ASP.NET (and I think some JSF implementations) does as well - 
serialization of the state in a hidden input field. I don't think it'd 
be that difficult to implement a custom tag that does this, wouldn't 
it?
