Trying out Content Security Policy and using the Report Only method and the data is sending a POST (See edits, supposed to be POST, but Request Headers say GET) to my page which I then use to email myself. In the browser developer tools I can see the data in the Request Payload, but I don't know how to access this scope. The FORM scope is empty and the GetHttpRequestData() doesn't show a Payload key.
How do I access the data in the Request Payload in ColdFusion?
EDIT: In the dev tools I can see in the network tab a POST to the page with 4 sections: General, Response Headers, Request Headers and Request Payload. I need to access the Request Payload data.

GetHttpRequestData contains Request Headers but not Request Payload. I did notice that the website I read said the Security policy would send the data via POST but the Headers say GET. Would that cause the issue? Should they be in the URL scope? Not at my machine at the moment.
So I was looking in the right spot, GetHttpRequestData but what I didn't realize was I setup the url to not have a trailing slash and my IIS Rewrite rules was redirecting to the / version of the page and the header data was being lost in the process.

I have an application where I am trying to send a post request with an added header.
resp=make_response(redirect(returnFilter(request.args,forms)))
resp.headers.add('foo','foo')
return resp
the returnFilter function is a custom function to make a link for the redirect and that works fine. I added a breakpoint at return resp to make sure it was adding the header after I noticed the problem and it does.
I caught the request it would send and it confirmed it did not actually add the header but I do not know why.
You are adding the foo: foo header to the response headers, but it looks like your screenshot is from request headers, did you look at the correct headers?
Some example code i wrote to test headers.add(...) method:
from flask import Flask, redirect, url_for, make_response
app = Flask(__name__)
#app.get('/')
def index():
return 'Hello'
#app.get('/header-test')
def header_test():
response = make_response(redirect(url_for('index')))
response.headers.add('foo', 'foo')
return response
app.run()
Request headers:
GET /header-test HTTP/1.1

As you can see foo: foo is there in response headers just like it should be.
Consider this view that generates an ico image:
from django.http import HttpResponse
from app.somewhere import Favicon
# View URL: `/<str:colour>.ico`
def favicon( request, colour ):
response = HttpResponse(
Favicon.render( colour ),
status=200
)
response['Content-Type'] = 'image/x-icon'
response['Cache-Control'] = 'public, max-age=31536000'
return response
Favicon.render() returns a valid byte stream, do not pay any attention on that.
Here is a link element in head of my HTML document:
<link rel=icon href=/7f9fa4.ico>
Now comes the question: why each time I reload the page, my browser, Chromium 73, makes a request to /7f9fa4.ico, instead of retrieving the icon from cache? If I will open /7f9fa4.ico in a new tab, first time request to the server would be sent, further my browser will retrieve an image from cache; now tell me what's wrong with the browser-caching system.
Here is a request (cookies and preferences are omitted):
GET /7f9fa4.ico HTTP/1.1
Host: localhost:8000
Connection: keep-alive
Pragma: no-cache
Cache-Control: no-cache
User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.86 Safari/537.36
Referer: http://localhost:8000/
And these are response headers:
HTTP/1.1 200 OK
Date: Mon, 03 Jun 2019 07:03:58 GMT
Server: WSGIServer/0.2 CPython/3.6.8
Content-Type: image/x-icon
Cache-Control: public, max-age=31536000
X-Frame-Options: SAMEORIGIN
Content-Length: 196
Console output (if it somehow could help):
[05/Jun/2019 09:17:42] "GET /7f9fa4.ico HTTP/1.1" 200 196
Also, if I will remove link element from head, browser will make requests to /favicon.ico (which in my case just mirrors /ffffff.ico) each time I reload the page with the same effect.
What you may find is that this request is being made to validate the cached content. I noticed that the request you sent to the server has Cache-Control: no-cache and Pragma: no-cache.
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control#Cacheability
no-cache
Forces caches to submit the request to the origin server for validation before releasing a cached copy.
So it forces caches to submit the request for validation.
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Pragma#Directives
no-cache
Same as Cache-Control: no-cache. Forces caches to submit the request to the origin server for validation before releasing a cached copy.
These state that the browser would be expected to send a request to your server for "validation" before it uses the cache icon.
now I am using play framework 2.3, how to share cookie on cors (cross domain)
i have play application on port localhost:9000 and i want to share cookies to my client running on localhost:5000
client cannt get the cookies
i try with this in play framework app:
response().setCookie(AUTH_TOKEN, authToken); //with setting on application.conf (session.domain="http://localhost:5000") cookies sent but cannt read by javascipt /failed
response().setCookie(AUTH_TOKEN, authToken,10000,"localhost:5000","/"); //fail

how the right way?
any one can help me?
You may need to use the Access-Control-Allow-Credentials header. If you are using AJAX/JQuery you must set
withCredentials = true
In your request. The server must also respond with header
Access-Control-Allow-Credentials: true
Note that if you do this you must specify a value for Access-Control-Allow-Origin. The browser will not accept Access-Control-Allow-Credentials header while Access-Control-Allow-Origin is a wildcard.
See the resources here:
https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS#Access-Control-Allow-Credentials

I was just trying to analyse all the HTTP header fields in Firefox plugin - Firebug. First I logged out from Stack Overflow and then cleared all the cookies from my browser.
Then I went to the Stack Overflow's home page. I mean while saw the HTTP request and response header fields. This is what I saw:

There is a cookie included in the request header. But as I said I have removed all the cookies from my browser. How is the cookie included in the request? What is actually happening here?
I did as Andy Davies told. I first cleared all the cookies, restarted Firefox and then went to www.stackoverflow.com. Firebug shows this:

If this is not the first request, then why is it not showing the first request?
Did you restart the browser after clearing the cookies as, from my memory, some browsers don't clear the cookies for any sites currently open?
The snippet you've posted looks like a JSON response part way through loading the page, so it is not the initial request for the HTML page.
When the HTML page would have been requested again, the Google Analytics cookie (which is what you've got above) would have been resent, so any subsequent components on the page will also get the cookie too.
Ok so AJAX POST requests work fine in Mozilla and Chromium, but fail in Opera. I get the standard CSRF error (403). I tried different versions of Opera and they failed in every one I tried. Btw, I'm using the jquery/django snippet that sets X-CSRFToken in the header, as verified in the "bad Opera request" below.
I made a view in a different project that was very simple and ajax post requests worked fine in Opera. I looked at the request details and see differences. The good request doesn't set any weird X-Opera-Info and other opera params even thought I'm using the same browser. If this is the issue, is there a way to remove those extra params? Or does anyone have any other advice or ideas on what the issue may be? I know it's not my view function because I tried just returning an HttpResponse immediately and even that gets 403'd. Thanks a million guys.

I recently ran into a similar problem. I was trying to do, for the first time, a post from AJAX on a view where Django wasn't sending a CSRF cookie. For reasons I can't explain, this was working on all browsers I tried except Opera.
This scenario is described in the Django docs, and they suggest using the ensure_csrf_cookie decorator.
Another thing you can do if it is too burdensome to wrap all the potential views with that decorator is to add something like this to your base template:
<script>
var csrf_token = "{{ csrf_token }}";
</script>
And then whenever you do an AJAX post, always include the key pair csrfmiddlewaretoken: csrf_token with your POST data.
Once I did the above, my posts with Opera started working.
Does it work if you disable Opera Turbo? These extra headers seem to be Turbo-related and perhaps this makes some kind of difference.
X-CSRFToken: {{ csrf_token }}}
value should be send from client in AJAX request HTTP headers to be recognized by Django
