varnish backend dns ttl

[Guillaume Quintard]

Hello there,

DNS resolution is done once and for all at VCL load, so you can just reload
instead of restart. IIUC, varnish will fail loading the VCL if more than
one IP is found though.

I would advise you to look ad vmod-named (
https://github.com/Dridi/libvmod-named) and vmod-gwist (
https://github.com/gquintard/libvmod-gwist) that could do what you need.
