  Login redirects are cacheable

When an AccessDeniedException is thrown and a handler handles the necessary redirect, we don't explicitly set cache headers that forces no caching of the response.

Today we only set 'private' which should stop proxies from caching the response, but we can be even more explicit and set both 'no-store' and 'no-cache'.

  Content URL cache does not invalidate cache remotely

DefaultContentUrlCache is using IObjectInstanceCache and not ISynchronizedObjectInstanceCache. Therefore, URLs are not removed from all instances in a load-balanced setup.

Reported from Content url caching not invalidating on synchronized sites (episerver.com)

How to reproduce:

  • Set up a load-balance environment with remote events.
  • Upload an asset.
  • Render link to asset in a view.
  • Access the view from both nodes and click the link.
  • Change the URL to the asset from one of the nodes.
  • Refresh the view on the other node and click the link.

{
	"name": "PageRegExValidationInvalidCase3",
	"baseType": "Page",
	"editSettings": {
		"available": true,
		"order": 0
	},
	"properties": [
        {
			"name": "String1",
			"dataType": "PropertyString",
			"validation": [
				{
					"name": "RegularExpression",
					"severity": "error",
                    "pattern": "[0-9]++",
					"errorMessage": "String 1: pattern is invalid"

				}
			]
		},
        {
			"name": "StringList1",
			"dataType": "PropertyStringList",
			"validation": [
				{
					"name": "itemRegularExpression",
					"severity": "error",
                    "pattern": "[0-9]++",
					"errorMessage": "String List 1: pattern is invalid"

				}
			]
		}
	]
}

Expected result: 
Content management is created with invalid pattern return 400- Bad Request.
