We are moving our server farm to AWS - and I want to fully test the new servers before sending them live traffic.
Question is: How would I trap all incoming traffic and copy it to the new servers?
For example: I know the URLs are in the access logs. How would I read the access logs in real time (or similar) and then send those URLs to the new server?
Obvioulsy the response from the new server would go back to the old server and be ignored.
All the servers are running Ubuntu, if it makes a difference.
