Chrome is rendering .txt files - google-chrome

All of a sudden, chrome (v 23.0) began rendering .txt files used to debug curl http requests. There is javascript and html in these files that used to be displayed as text. Now, some of the javascript is causing a redirect. Safari and Firefox are still working as before.
I'm concluding that this is a setting, but did not find any thing related in Chrome settings.
Any ideas where to change a setting like this.

POST 405 Not Allowed with Particular XMLHttpRequest and ASP

I am working on a JavaScript application, where I want to read data from an XML file and post them into a HTML file.
My code is producing the following error:

Based on this posting I created a new 'Handler Mapping' and I also adjusted the 'Handler Mapping' for 'StaticFile' to allow the methods: GET,HEAD,POST,DEBUG,PUT,DELETE.
The IIS server was restarted but still the error message appears and the only methods allowed are: GET, HEAD, OPTIONS, TRACE.
So, there is some configuration file or 'Handler Mapping' overriding my settings, or I simply did not consider.
Any suggestions on how to tell the IIS to accept my settings for this XMLHttpRequest?

Browser Cache, and Ember Data

I'm seeing some interesting Chrome behaviour, and I need a hand deciphering what's going on and possibly how to work around it effectively.
Here's the scenario:
User views a list of resources (e.g. TODO items)
User modifies a few of them
User navigates away from my Ember application and then returns via the back button
User sees previous state of resources
When making the initial request for the resources, I'm seeing something like this coming from the browser:
Request
Request Method:GET
Request URL:https://api.server/some_resource?ids%5B%5D=7495&ids%5B%5D=6420&ids%5B%5D=6787...

And the subsequent request when returning to view the resources:

Notice on the subsequent request that Chrome is reporting the status as "200 OK (from cache)", which seems to be why I'm seeing this happen.
My homework on this problem has turned up a seemingly related question on SO, which in turn links to You Do Not Understand Browser History. OK, so Chrome isn't validating the etag when the back button is used. How do I work around this? Disabling caching of requests really sucks, and it seems like there should be a more elegant solution.

What are the causes of HTTP GET (Cancelled)

My app needs to access a resources as in the Request URL however I can see in the Chrome network console that the request is GET (Cancelled)
Request URL:http://localhost:6001/_api/
Request Headers CAUTION: Provisional headers are shown.
Accept:application/json, text/javascript, */*; q=0.01
Cache-Control:max-age=0

Is there anything wrong in the request? If I access the Request URL and paste it in the browser, the JSON string is returned properly. What could be the reason?
Update:
Prior to the request above here there is a request for this:
Request URL:http://localhost:6001/_api/_session
Request Method:OPTIONS

But the status was: A wildcard '*' cannot be used in the 'Access-Control-Allow-Origin' header when the credentials flag is true. Origin 'http://127.0.0.1:6001' is therefore not allowed access.
You are mixing 127.0.0.1 and localhost which could make it look like xss. Use one or the other but not both.

CORS error happens only on certain XHRs in Chrome

We have an SPA that draws more javascript modules from a separate backend server, assisted by Require.js. By nature of the XHR loading procedure, pre-flight OPTIONS requests are made to the backend server and the Access-Control-Allow-Origin response is perfectly valid. The process of login and initial module loading work just fine, as expected.
XHR finished loading: "http://backend.cloudapp.net/api/modules/resourceA".
XHR finished loading: "http://backend.cloudapp.net/api/modules/resourceB".
Funny thing is, certain subsequent actions that call for more modules would unexpectedly raise a CORS error in Chrome.
XMLHttpRequest cannot load
http://backend.cloudapp.net/api/modules/resourceC. Origin
https://frontend.cloudapp.net is not allowed by
Access-Control-Allow-Origin.
Which does not make sense, since the previous modules loaded just fine. Even the actual OPTIONS preflight came back proper for resourceC. Some other places in the UI have their modules loading fine too. And Firefox does not appear to suffer from this problem. Has anybody experienced similar CORS errors?

(And browser blocks further action)
Given that Chrome has gone through so many version updates, in addition to us deploying some module resources in a different package manner now in different AWS infrastructure, we no longer experience this problem now.
Inspired from my answer here
It might be worth investigating if any of the failing XHRs are sending any peculiar unicode character. In our case, one of our user's name contained a unicode character and our HTTP proxy wasn't handling it properly thereby leading to a CORS error.

H.264 Streamed Video Works in Chrome 23 but not Chrome 24, different request headers... same cherrypy backend

On the site I'm currently working on, we use html5 video with h.264. If it's not available we use a flash fallback. The flash fallback is working just fine in both chrome 23 and 24, but the html5 video only works in chrome 23.
I opened the video file in it's own tab (which chrome then has a simple bootstrap snippet of html to play it) in each version of chrome and saved the request and response information. It makes three requests actually but I find teh first one to be the most interesting. Here is the header information for the request and response for both.
Chrome 23:

Has anyone else expierenced this? I'm willing to do further tests as requested as well.
You may fix this problem by doing the following:
There is an option in chrome://flags called "Disable hardware-accelerated video decode" enable it.
https://productforums.google.com/forum/?fromgroups=#!searchin/chrome/mp4/chrome/ilqhiTTZcaY/hkPGA3GK6BIJ
And this is a bug filed three weeks ago: http://src.chromium.org/viewvc/chrome?view=rev&revision=178906. According to its status it is “Fixed”. However, later on in the comments it is saying the fix might be pushed for version M25 and is fixed with version 26.0.1395.1.
As a test, I have downloaded version 26 of Chrome (the developer version), (re)disabled the “Disable hardware-accelerated video decode”, and everything works fine. If you want to do the same, visit Chrome’s release page and choose “Dev channel for Windows”.
