# MVC.NET::Ping
An MVC ActionResult that should indicate the health of your service.
## Usage
Here is a simple example (see `Ping.Driver`)
public ActionResult Ping()
{
return new PingResult(
new PingOpts
{
Check = () => false,
ErrorText = "aw snap."
});
}
## Options
When building/mounting your application, use the configuration,
specify:
* `Version` is an accessor for your application version. `VERSION`
would be a good idea.
* `CheckUrl` is a url that `ping` will fetch and run `OkRegex` on. If
the match is ok, we're good. You must specify `CheckUrl` and
`OkRegex` togather. `TimeoutSecs` is the amount of seconds we wait
until spitting out an error.
* `Check` will accept a block to run. This is a good alternative to
`CheckUrl`: run a couple of sanity checks to indicate you're good.
* `OkCode`, `ErrorCode`, `OkText`, `ErrorText` are configuration for
you to use, to configure against LB quirks. The default config should
work against ELBs (Amazon elastic LB).
## Headers
`ping` will output intelligent headers. First `x-ping-error` will try to
explain why ping failed.
Next, `x-app-version` will expose the current deployed version of your
app. This is good in order to validate nothing crawled up to production,
as well as validation for post-production deployment.
`ping` will bust any browser/client cache for you.
