Description

remap.config claims to support tunnel:// URLs, but this seems to be totally broken. At least I can't get it to work.

If I start with a remap.config like this:

map tunnel://www.example.com/ tunnel://foo.com/

What happens is that inside remap_parse_config_bti it does a DNS resolution and seems to try to ass mappings for each resolved address. Although this seems like a bad idea, it doesn't work because getaddrinfo returns entries for IPPROTO_UDP and IPPROTO_TCP and the loading code fails when it tries to add duplicate mappings (it adds one for each address result and fails to check the protocol field).
