Issue:
We were having issue with one of the ajax request in webkit browsers ( Chrome, Firefox, and Safari).
scenarios working:
1. If we configure chrome/firefox with Fiddler and enable https decryption in fiddler it works as expected.
2. Works properly in internet explorer.
We were able to see response on page, but if you go to networking tab and check response it's null and request is not complete it's spinning. we were thinking it's more of webkit browser decoding issue.
Please share if you have any idea how to fix or what might be causing this issue, any input will be appreciated.

The issue was server side, i was getting extra data in JSON response and data binding was not happening properly in chrome, firefox and safari.
Whereas IE is having loose binding policy i guess that's reason it was working in IE

I'm a bit unsure what it happening here but ill try to explain what is happening and maybe write a better question once i figured out what i'm actually asking.
I have just installed Varnish which seems awesome for my request times. It is a Magneto 2 store which I have followed the default configuration within dev docs for varnish.
My Issue
Currently my issue is that the browser seems to be caching the page until i click refresh. I believe i am successfully flushing / purging the cache with magento / varnish. As when using Curl to request the page i can see a new page is generated each time i flush cache and just serves cached page if i don't.
Within chrome and firefox however on my client pc however the whole page markup seems to be cached (when clicking a link to page or pasting url in browser) until clicking refresh which seems to reload the real page. When deploying new static files etc as the old resources are still in the cached markup and the new location for resources is signed e.g. version1234/styles.css and not matching the markup i get CSS less pages until client clicks refresh and loads the actual markup from server?
How can i setup caching so that this does not happen?

You should adjust your server configuration so that those are not sent for PHP. Most likely you have a configuration block in nginx or .htaccess that applies to the whole website, as opposed to just static files.
I am not using the SBT, but making direct REST calls with Abdera to the current version of Connections on IBM SmartCloud. REST URL in question: https://apps.na.collabserv.com/search/serviceconfigs
Observations
When testing from my laptop (using Firefox and the REST client add-on,) this works as expected. I get back an ATOM feed.
When testing from a server (on a different network,) using the same method (Firefox + REST client,) I get back HTML that is a log-in page.
In addition, I get this same result when I call the URL from a Java program on the same server.
In all cases, I am using the same credentials with basic authentication.
Update: If I log into SmartCloud first, on a separate tab in Firefox on the server, then call the URL as before, from another tab, it works. I get the ATOM feed as desired. Naturally, this is unsuitable as a solution, but I present it as additional information that could lead to an actual solution.
Update: Further testing shows that the local (laptop) log-in exhibits the same behavior as the server. A form-based log-in is required from the same browser, then subsequent REST calls work.
Update: Here is a relevant simplified code snippet:
private static Abdera ABDERA = new Abdera();
private static AbderaClient ABDERA_CLIENT = new AbderaClient(ABDERA);
...
String host = "https://apps.na.collabserv.com";
ABDERA_CLIENT.addCredentials(host, AuthScope.ANY_REALM, "basic", new UsernamePasswordCredentials("user", "password"));
...
ClientResponse response = ABDERA_CLIENT.get("https://apps.na.collabserv.com/search/serviceconfigs");
Summary
It appears that something about the originating server or the call is causing SmartCloud to respond with a log-in page. Whereas, the same call and credentials from my laptop, work as expected.
Question
Where should I start to trouble-shoot this? How can I build the client credentials to allow programmatic log-in?

#Grant is your login using SAML? I could see this redirect happening. also could be TFIM related... maybe you should grab the auth on a different page, store the cookies, and then try connecting to the endpoint above.
I'm stumped, my website was working fine and now on Firefox suddenly the redirects stopped working.
I've tested IE and Chrome and going to /login redirects me to /dashboard however on Firefox the page is blank (no output sent) and no errors are logged. So this is why I'm assuming it to be a browser related issue. It might be due to a firefox update, but not sure how to confirm that.

It all looks pretty standard to me, however FF stays stuck on /login Am I missing something?
This behaviour is both on my local windows host and my remote amazon Linux web-server. The body is empty...
How could I go about debugging this?
The Expires header field in the response is really off. Firefox probably does not bother to render stale responses.
Please check the system time in your server. It is possible it is an Amazon problem, but it is also possible that one of the server users set the system time.
You can look into setting up a Network Time Protocol (NTP) client to run regularly (with ntpd), if you don't have that yet.
I would fire up Fiddler to see what bits actually went over the wire. Among other information, Fiddler will show what content type is actually used during the HTTP request / response.
This could be related to the fact that there is no extension. Firefox could be having trouble determining if this is a document or folder. Try firebug and see what URL Firefox tries to request after the redirect.
I'm getting some odd response back from shopify ajaxapi for jsonp.
If you cURL a Shopify ajax api location
http://storename.domain.com/cart.json?callback=handler
you will get a jsonp response. But something is breaking the same request in browsers.
It appears to be related to compression? Here are some responses from each browser when attempting to call the jsonp as documented.
Firefox: The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.
Internet Explorer: Internet Explorer cannot display the webpage
Chrome/Safari/Webkit: Cannot decode raw data, or failed (chrome)
Attempted use via jquery:
$.getJSON('http://storename.domain.com/cart.json?callback=?', function(data) { ... });
// Results in a failed request, viewable network request panels of dev tools
Here is some output from cURL including response headers:

We're having some really strange problems with IE7, and only IE7. When trying to replicate the issue it only happens with native IE7, not when running IE7 mode in IE8/9, so please remember that if you try to replicate this issue.
The problem is the following:
We're polling for a response from the server with AJAX. The user posts something that the server may have to work on for a bit, so every 5 seconds or so a request is sent check if the server is done. This works fine in every browser, except native IE7. The problem is that it never stops "loading". When checking the requests with Fiddler2 we see that it does two requests and then nothing more. It stops doing anything when still in PENDING mode. In a sain browser it keeps on polling, and then stops when it gets "CONFIRMED". The really weird thing is that it does its final request and returns as normal, only, and really only, when you open a new tab.
It's not that the page needs focus or anything, clicking around randomly does nothing. I'm asking here because I can't even reproduce the issue using a local instance of the project.
Here are the headers sent back by the server:
These are the headers for the response on the production machine. This was the last response gotten. It loads indefinitely until you open a new tab (just an empty new tab!), then the final request is made and everything works out.

If you want to try it you can go to videofy.me, get a new account (it's really easy), when logged in go to videofy.me/blogger/settings/direct_publishing. Choose a blog platform in the first dropdown, press "activate" and write something into the username/password fields that appear, then press the green button and wait forever. After 45 seconds or a random amount of time open a new tab, and see that the request is magically finished.
I'm guessing it has to do something with IE7 cacheing the request, and then something is released if a new tab is opened. But it's just a guess, and googling returns nothing related. I'm posting here because it's so obscure that I hope someone here knows anything about it.
