FYI I'm using Tomcat v7.x. I guess I misunderstood what happens when I use sendRedirect() - it sends a new request, not a new response - but the effect is the same. That was what I came away with when I read this:
http://javarevisited.blogspot.com/2011/09/sendredirect-forward-jsp-servlet.html In any case, I gave up on using the header to pass additional items from the server to the browser and ended up just using cookies. Unless someone shows me otherwise, everything I saw online showed how to use jQuery/xhr/your JS tool of the month to get header values from a GET/POST response; meanwhile I never figured out how to extract those values after a document was rendered in a traditional MVC app. On Thu, Sep 8, 2016 at 11:22 AM Christopher Schultz < ch...@christopherschultz.net> wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA256 > > Joe, > > On 9/6/16 3:36 PM, Joe Tseng wrote: > > I inherited a codebase that calls > > HttpServletResponse.sendRedirect() to another page after a user is > > successfully logged in.
