Currently, if you wish to create bookmarkable URLs in Seam, when you
submit a form with validation that fails, the form URL will display
the JSF view ID (eg. /faces/store/buy.jsf), at this point Seam will
have to send a redirect to the browser to redirect them back to the
proper URL (eg. /store/buy). This is alright, but it causes wasted
bandwidth, increased client wait time, and extra CPU usage. On a
high-load system, this can matter a lot.
You almost always want to redirect after a POST to keep the browser in
a sane condition. That being said, we should be be rewriting
outgoing URLs even in this case, and if we aren't I would think it's a
bug we need to fix. I'll take a look and see if I observe the same
behavior.
