You can check the process exit code by curl. FYI http://curl.haxx.se/libcurl/c/libcurl-errors.html

curl  "http://www.my.damn.unreachable.server.com:9090"
if [ "$?" = "7" ]; then 
    echo 'connection refused or cant connect to server/proxy';
fi

You can check for exit status of curl. For example:

curl -I -A "Chrome" -L "http://localhost:8080"
curl: (7) Failed connect to localhost:8080; Connection refused
[[ $? -eq 7 ]] && curl -I -A "Chrome" -L "http://localhost:9090"
