page-replay
Replay page from local cache, honouring load behaviour from multiple domains.
Usage example
Cache http://mywebsite.com/page
and serve all resources with a three second delay:
./replay.js http://mywebsite.com/page --domains mywebsite.com,cdnjs.com,something.static.com --delay 3000
Resources will be save into the ./data
directory, and the page itself as an .html in the working dir - you can then edit it for testing if necessary.
