How can I read the value of APP_REQ from my pwd.html using Javascript? Its not part of query string or URL but it is part of request.
This isn't possible, unless the server were to include this value in the content of pwd.html itself. This requires something server-side like PHP or Node.js.

I'm working on a React App which needs to fetch data from an Api.
I made it work with fake data.
fetch('https://jsonplaceholder.typicode.com/posts')
.then((response) => {
console.log(response);
return response.json();
})
.then((json) => {
return json;
})
Now i wanted to get data from our local Api with Apigility.
fetch('http://localserver:8081/news')
.then((response) => {
console.log(response);
return response.json();
})
.then((json) => {
return json;
})
But i get net::ERR_ABORTED 403 (The origin "http://localho.st:5000" is not authorized). The app was created with create-react-app and gets served by its run script.
Now the thing is it works, when i enter http://localserver:8081/news in Firefox and Edge. I receive the json data. The same when trying it with my phone, curl or an api tester.
This is the answer when trying to fetch from the app:

And when calling from browser:

Content-Type: application/hal+json

I've read about setting up a proxy to get CORS calls, but i wondered if there are other solutions to this problem.

Create-React-App comes with a simple way to handle this: add a proxy field to your package.json file as shown below. In this case, a request is made from server A to server B
"proxy": "http://localserver:8081/",
You can run a local reverse proxy to get the API calls from the same origin (say mapping localhost:3000/api/news to localhost:8081/news) but then it'd probably be easier to set up a CORS proxy.
You could try to make the API JSONP and circumvent the same origin policy that way, but this is likely also more hairy than setting up a CORS proxy.
Long story short: Whenever you make requests across origins, CORS needs to be set up.
I'm running a Jenkins server behind an Apache Proxy.
I'm using Chrome as my browser
Now in a couple of places I have javascript code that looks like this.
console.log("Looking for " + log_url)
$.ajax({
url: log_url,
dataType: "xml"
})
.done(function(xml) {
console.log("FOUND " + log_url);
})
(with something more interesting going on in the "done" section of course)
Now, in one place it works fine, that's when it's in a javascript file in jenkins userContent (a folder where you can put files you want jenkins to serve up via HTML) which is loaded from HTML on a jenkins generated page.
Looking at the headers I see

So it's sending a GET request, headers are being served up as I have set them in the Apache proxy, and the page works, lovely.
However, if I do the same thing in a javascript file loaded by an HTML page which is in userContent, I see the following headers

So it is sending an OPTIONS request, which is failing, so the code fails there and the page doesn't work (incidentally it works fine when I don't
So I have two questions.
1) Why do I see an OPTIONS request in one case, but not the other?
2) How can I make it work?
Now I know that an OPTIONS request is sent when the jquery is cross-domain, but I don't see how this would qualify as cross domain.
Everything is served up by the same server, the only difference is that in one case the parent page is generated by jenkins at the url /jenkins/job/WPF-TryBuild/[job_number]
whereas in the failing case the parent page is an html page served up by jenkins at
/jenkins/userContent/WpfReports/msbuild/MSBuildLog.html
(Incidentally, changing Access-Control-Allow-Origin from null to * makes no difference in either case)
I added ASP.NET javascript bundling and minfication to our website, and have discovered that now if I refresh the website, the bundled javascript file is downloaded as gzip but never uncompressed by the browser, so the site of course doesn't work since the javascript is still compressed. If I refresh again, the site is fine. Refresh again, corrupt. Back and forth. This is ONLY happening in Chrome and Safari, but not in IE.
Watching in Fiddler, IE gets the javascript the first time, and subsequent refreshes return 304 not modified which is correct. Chrome / Safari refreshes continually return 200 for each refresh.
If I run my website locally hosting it in IIS Express, this problem does NOT occur. It's only in our other QA, Staging and Production environments where the website is hosted by IIS 7.5.
I did a Fiddler compare of the good Chrome request and the bad Chrome request to see what's different. They are identical except the bad request has the "If-Modified-Since" header.
The response from the server when the "If-Modified-Since" header is there has a Content-Type of "application/javascript", and this is what I think is causing the problem, the browser doesn't know it should uncompress the response body.
Here is the GOOD request and response (body omitted for brevity):

Thank you for your help.
Is someone can check :
http://umberto073.cloudapp.net/ajax/ajax/#!/index.html (Click on It, then Menu on left, then Gallery)
The page should load a div (with .load jQuery) like This one :
http://umberto073.cloudapp.net/ajax/ajax/gallery-3col.html
I have a page served by HTTP. Client code sends AJAX-requests for authorization to the same domain, but on HTTPS. (so it is CORS).
FireFox generates this request: // domains and cookies are changed

FireBug shows that OPTIONS request succeeded, but does not fire GET request after it:
What is wrong in my response?
Qantas 94 Heavy, you're right. There should be only one Access-Control-Allow-Origin header with only one domain: domain, that specified in Origin request header.
This is right answer that firefox accepts:
