I need to test whether my 304 responses are working, but my development environment is very difficult on no-cash.
Is there an easy way to modify the maximum-age value of the cash-control header?
I probably have a console command in Chrome (or an extension, or FF), which has been modified-modified-because the headers then send the request. Probably a paste in a telnet connection?
If you have access, then the easy way is:
