for user posting via (http post etc.),
more and more sites' server now reponse a 302 redirect to bring to the new posted content automatically showing to user,
but I still see quite many severs still simply response a page w/ a link for the user to click on, in order to see their post.
Ironically some are popular web2.0 blog sites (livejournal, blogger etc.) who emphasizing the best user experience?
