To show under what conditions the application cache fires.

We consider the following interference modes:

• No DNS Reply - No UDP response from DNS server
• No DNS Answer - A DNS response is sent with no answer section
• IP RST - a reset packet is sent in response to the client's TCP SYN
• No IP Response - No syn-ack packet is received by the client
• No HTTP Response - The connection is closed after the client request
• MITM - An incorrect SSL certificate is presented by a malicious server

Current behavior for an HTTPS site using a fallback appcache appears to be:

Browser	AppCache	No DNS Reply	No DNS Answer	IP RST	No IP Response	No HTTP Response	MITM - 404	MITM - Block Page
Chrome/41	Yes	Activates	Activates	Activates	2 min timeout	Activates	Warning	Warning
Safari/5.1	Yes	Activates	Activates	Activates	3 sec timeout	Activates	Activates	Activates
Firefox/36	Yes	Activates	Activates	Activates	5 min timeout	Activates	Activates	Activates
IE/11	Yes	Activates	Activates	Activates	1 min timeout	Activates	Warning	Warning

Current behavior for an HTTPS site using a primary appcache appears to be:

Browser	AppCache	No DNS Reply	No DNS Answer	IP RST	No IP Response	No HTTP Response	MITM - 404	MITM - Block Page
Chrome/41	Yes	Activates	Activates	Activates	Activates	Activates	Activates	Activates
Safari/5.1	Yes	Activates	Activates	Activates	Activates	Activates	Activates	Activates
Firefox/36	Yes	Activates	Activates	Activates	Activates	Activates	Activates	Activates
IE/11	Yes	Activates	Activates	Activates	Activates	Activates	Activates	Activates
