Hi Val,
Got it. Thanks for the response. A good guideline. I needed that validation.

This is how HTTP works. What you're seeing is the "target" response of the
redirection, not the "redirect" response (which has a 301 status code and a
"Location" header).
Again, this weird hybridation of classical web pages / AJAX behavior is
probably the root of all evil here :). IMO the way to go here is to not
redirect from the server, this is a decision to be made by the client (and your
client knowing why it fetched the data, it probably also knows where to go next
:) ).

Hi Val,
Thanks for the answer. I still have one more issue related to this logic.
When I set the :location at the header onn the server side, what I see on the
client console (Chrome) is as follows (logging the response from the server):
I don't see the location key/value, instead, I see the whole page in HTML. Any
hint? tried with different doc-types.
{:status 200,
:success true,
:body "\r\n\r\n\r\n\r\n \r\n \r\n
--\r\n",
:headers {"date" "Sat, 12 Sep 2015 18:27:30 GMT", "x-content-type-options"
"nosniff", "server" "undertow", "x-frame-options" "SAMEORIGIN", "content-type"
"text/html; charset=utf-8", "connection" "keep-alive", "content-length" "3928",
"x-xss-protection" "1; mode=block"},
:trace-redirects ["/person" "/person"],
:error-code :no-error,
:error-text ""}
(defresource post-person-resource
:available-media-types [ "application/clojure"]
:allowed-methods [:post]
:post! (fn [context] ())
:post-redirect? (fn [ctx] {:location "/job"})
ON THE Client side, I solved the redirect issue with the following code:
(.assign js/location "/job")
But I couln't find the location in the header. So I hard-coded it here!
Thanks for the response.
Regards,
Hari

[ClojureScript] Re: Redirect in a SPA on the server side.
Because you're working with AJAX, you do not want your server to redirect. You
want to just send the data to the server, and then change the URL of the page
with something like
window.location.href =
