The ProxySG does not support the use of a hosts file. However the ProxySG does offer a way of simulating such behavior by defining a forwarding host. This can be done via the CLI or the Management Console.
Enter configuration commands, one per line. End with CTRL-Z.
ProxySG#(config forwarding)create host "Https_Server" 10.10.10.10 tcp=443 ssl-verify-server=no server
You can set the following policy rule in the local policy file. If you do not know how to place this into the local policy file, see 000010101
If you would like to resolve an http site, create follow forwarding host instead:
create example_server 10.10.10.10 http=80 server
Note: Detailed info on creating a rule to resolve an http site is available at 000009121
