-# Mongoose-based HTTP load balancer
-
-## Configuration
-
-Load balancer is configured with command-line flags.
-
-### Global flags
-
-* `-p port` – TCP port to listen on. Default: 8000.
-* `-l log_file` – path to the log file. Default: none.
-* `-s ssl_cert` – path to SSL certificate. Default: none.
-
-### Backend configuration
-
-Main flag is `-b uri_prefix host_port` – it adds a new backend for a given
-URI prefix. Example: `-b /stuff/ 127.0.0.1:8080` will route all requests that
-start with '/stuff/' to a backend at port 8080 on localhost. There is a special
-syntax for `uri_prefix` that allows you to change the URIs that get passed to
-backends:
-
-* `-b /stuff/=/ 127.0.0.1:8080` – for '/stuff/thing' backend will see '/thing'.
-* `-b /stuff/=/other/ 127.0.0.1:8080` – '/stuff/thing' => '/other/thing'.
-
-Also there are few per-backend flags that can be placed before `-b` and apply
-only to the next backend:
-
-* `-r` – instead of proxying requests load balancer will reply with 302 
-redirect.
-* `-v vhost` – match not only URI prefix but 'Host:' header as well.
-
-### Example
-
-```
-load_balancer -s path/to/cert.pem \
-  -v example.com -b /site/=/ 127.0.0.1:8080 \
-  -b /static/ 127.0.0.1:8081 \
-  -b /static/ 127.0.0.1:8082
-``` 
-
-In this example requests to 'example.com/site/' will be forwarded to the
-backend on port 8080 with '/site' prefix stripped off and requests to
-'/static/' on any virtual host will be balanced in round-robin fashion between
-backends on ports 8081 and 8082.
