Hello,
I've created a patch that mimicked tcp_table. however, the table lookups
are directed to a unix domain socket instead of tcp servers.
Actually, the patch itself is a modification of the source code of
tcp_table.
Map names have the form usock:/path/to/socket
If i'm not on the right path, can i request similiar feature.? (it would
be great to have both tcp|unix-domain-socket_table)
tcp_table is great, its simple protocol allows us to talk to various
applications.
This really sounds like a name space design issue, since the
map-specific protocol does not change.
foo:tcp:host:port
foo:unix:/pathname
foo:tls:tcp:host:port
This needs further thought.

I have another scenario
tcp:host:port
tcp:/path/name
The reason why i wanted this feature is, by using unix domain socket i
can protect my backend server from interference on multiuser environment.
while tcp server is adequate for my single administrator/user
environment server.
TIA
