[![Build Status](https://travis-ci.org/gregwhitaker/ratpack-defaultcachecontrol-example.svg?branch=master)](https://travis-ci.org/gregwhitaker/ratpack-defaultcachecontrol-example)

An example of setting a default cache-control header in a [Ratpack](https://ratpack.io) application.

## Running the Example

1. Run the following command to start the application:

        ./gradlew run

        

2. Run the following command to call the `/api/v1/get` endpoint with its own cache-control header set:

        curl -v http://localhost:5050/api/v1/get

        

    Notice that the `Cache-Control` header is set to a value of `3600` seconds, which is the value that was explicitly set in the handler.

        *   Trying ::1...

        * TCP_NODELAY set

        * Connected to localhost (::1) port 5050 (#0)

        > GET /api/v1/get HTTP/1.1

        > Host: localhost:5050

        > User-Agent: curl/7.54.0

        > Accept: */*

        >

        < HTTP/1.1 200 OK

        < Cache-Control: max-age=3600

        < content-type: text/plain;charset=UTF-8

        < content-length: 35

        <

        * Connection #0 to host localhost left intact

        

3. Next, run the following command to call the `api/v1/getwithoutcache` endpoint:

        curl -v http://localhost:5050/api/v1/getwithoutcache

        

    Notice that the `Cache-Control` header is set to a value of `1` second, which is the default value set by the filter.

        *   Trying ::1...

        * TCP_NODELAY set

        * Connected to localhost (::1) port 5050 (#0)

        > GET /api/v1/getwithoutcache HTTP/1.1

        > Host: localhost:5050

        > User-Agent: curl/7.54.0

        > Accept: */*

        >

        < HTTP/1.1 200 OK

        < content-type: text/plain;charset=UTF-8

        < content-length: 61

        < Cache-Control: max-age=1

        <

        * Connection #0 to host localhost left intact
