Varnish: Do not cache 404 error pages

If Varnish Cache is caching 404 error code pages from the backend, you can change this behaviour by adding this to the vcl

In the vcl_fetch section add this:

if (beresp.status == 404) { 
    	set beresp.ttl = 30s; 

You can change 30s to 0s if you do not want to cache 404 error codes at all.

I prefer to cache them for a short period of time, that way I can protect my back end from dealing with that load.
