All,
It appears that squid ipcache only keeps one address per name.
This is a problem when proxying to sites that have multiple A
records. In the event that one of the addresses is unavailable and
squid has cached that address it will continually return site
unreachable even though a connection to the host is possible.
This is a mis-feature.
Most DNS aware clients will try each address returned from DNS in
succession. BIND implements a perfectly functional IP address
cache that follows all the "right" rules. I'm thinking about
ripping out the whole ipcache system and replacing it with a simple
call to gethostbyname.
OK, I've got my flame suit on now.
