Yep, that's a well known issue. It's caused by the fact that JSF uses 
internal forwards a lot. When the browser POSTs data to /foo.jsf the 
server-side code can decide to render page /bar.jsf back to the user. 
However what the browser sees is that it POSTed to /foo.jsf and got back 
some content. It doesn't know that the content was generated by page 
/bar.jsp.

A solution is to mark your JSF navigation rules with "<redirect/>". When 
the code handling the POST decides to navigate to bar.jsp it will then 
send an HTTP redirect message back to the browser telling it to fetch 
bar.jsp, which fixes the problem. However that has a number of 
drawbacks, of which performance is one.

Note that this isn't really a JSF issue as such, more a problem with any 
framework that uses "forwards" within the server. I don't know PHP or 
ruby-on-rails or Tapestry but would expect them all to have exactly the 
same issue.

What is really needed is some extension to HTTP to allow the served page 
to tell the browser what to display as the page url. However that may be 
undesirable for security reasons..
