Add an option to avoid cache effect

As discussed here: https://github.com/swagger-api/swagger-ui/issues/2203#issuecomment-225065423

I would like to avoid cache effect with Internet Explorer By default, IE will cache json answer and If I do this sequence on a CRUD ReST API I’ve not the expected result

• get items => res A
• post new item => res B
• get items => res C

In my case, res A == res C but a new item is expected as res B is a success (I don’t reproduce on another browser than IE).

@fehguy suggest:

Create a request interceptor and set the headers before the request is sent:

var interceptor = {
  requestInterceptor: {
    apply: function (requestObj) {
      var headers = request.Obj.headers || {};
      headers['If-Modified-Since'] = 'Mon, 26 Jul 1997 05:00:00 GMT';
      headers['Cache-Control'] = 'no-cache';
      headers['Pragma'] = 'no-cache';
      return requestObj;
    }
  }
};

// assign the request interceptor in the UI
new SwaggerClient({
      url: 'http://localhost:8000/v2/petstore.json',
      requestInterceptor: interceptor.requestInterceptor,

I have not tested this solution but I like it. As it is a common issue, I would like this as an option.

In Chrome, there is an option to “disable” browser cache:

I am using $ref tag to embed the yaml schema file. It loads it for the first time , but doesn’t reflect any subsequent updates to that remote reference.

I can confirm this. I am experiencing exactly the same issues. Even force-refreshing the browser (CTRL+F5 under Chrome) does not refresh the stale referenced file. The only way to get it refreshed is to wipe out whole browser data cache.
