HAProxy is commonly used for load balancing, ie. you have a number of web servers and you wanted to distribute requests between them and seamlessly handle things like when a server goes down.

Configure HAProxy in front, and it'll forward connections (hence, it is a proxy) in such a way that connections will be spread between servers.

In practice, there are tons of configuration and complexities to fit specific needs. I'd start by taking a look at the docs. Here is an example of HAProxy being used as, well, a proxy to forward http connections. If you add more servers it'll load balance between those servers. There are more examples spread out through the documentation.

It's not very clear what you're looking for. Haproxy does many different things so there's no single response. I suggest you take a look at the architecture manual. It's quite old but will give you some concrete examples of what you can do with it.
