ajax - Unable to add custom header to response -

i unable add custom header response returned render():

response = render(request, 'my_template.html', {'ctx1': 1, 'ctx2': 2}) response['my-custom-header'] = 'abc12345'  return response 

this response ajax request initiated using jquery's $.get(). on chrome, response has template rendered properly, not have custom header. if print response object before returning, see has custom header.

i thought issue because of this answer, added django middleware add header responses:

class customheadermiddleware():   def process_response(self, request, response):     response['access-control-expose-headers'] = 'my-custom-header'     return response 

all responses have header access-control-expose-headers: my-custom-header, still see issue.

my request local; i'm using django development web server.

if send non-ajax request, whatever custom header add in django visible in response on chrome. issue seems limited ajax requests.

i using django 1.11.4 , python2.

[edit]

if capture response in wireshark, see not have my-custom-header. furthermore, if add custom header response dictionary in above middleware, header shows in wireshark , visible in chrome. seems django issue responses ajax requests.

this issue unrelated ajax. calling view using this template tag. custom response headers lost because of line 32 in code.
