I was quite fascinated when i read about Frontend SPOF. Had a basic idea earlier but this made me more aware.
A nice to have feature for pagetest would be to test for this. While making tests, I would like to specify how certain urls and/or hostnames should behave.
The behavior could be one of the following :-
[list]
[]Inject a specified lag
[]Make the DNS lookup timeout
[]404 these hosts/urls
[]500 error to these hosts/urls
[*]make them stall forever until browsers default timeout reaches
[/list]
As i understand at the moment you are only observing the packets… but hacking the connection would be nice feature addon
