# Plack::Middleware::Try

## SYNOPSIS

```perl
enable 'Try',
    catch => sub {
        if ($_[0] =~ /Query execution was interrupted/) {
            return [ 503, [ "Content-Type", "text/plain" ], ["Service Temporarily Unavailable"] ];
        }
    },
    finally => sub {
        warn $_;
    };
```

## DESCRIPTION

Plack::Middleware::Try is a Plack Middleware for handling exceptions thrown by an application.

For example, when an application dies unexpectedly, it should return 500 Internal Server Error generally. But some cases like DB execution timeout which doesn't always fail, it could return 503 Service Temporarily Unavailable.
