Can an AJAX response set a cookie

Question

Can an AJAX response set a cookie   If not  what is my alternative solution   Should I set it with Javascript or something similar

Yes  you can set cookie in the AJAX request in the server-side code just as you d do for a normal request since the server cannot differentiate between a normal request or an AJAX request   AJAX requests are just a special way of requesting to server  the server will need to respond back as in any HTTP request  In the response of the request you can add cookies

For the record  be advised that all of the above is  still  true only if the AJAX call is made on the same domain  If you re looking into setting cookies on another domain using AJAX  you re opening a totally different can of worms  Reading cross-domain cookies does work  however  or at least the server serves them  whether your client s UA allows your code to access them is  again  a different topic  as of 2014 they do

According to the w3 spec section 4 6 3 for XMLHttpRequest a user agent should honor the Set-Cookie header  So the answer is yes you should be able to   Quotation      If the user agent supports HTTP State Management it should persist    discard and send cookies  as received in the Set-Cookie response   header  and sent in the Cookie header  as applicable

Also check that your server isn t setting secure cookies on a non http request   Just found out that my ajax request was getting a php session with  secure  set   Because I was not on https it was not sending back the session cookie and my session was getting reset on each ajax request
