| 3.3 Choosing the Caching backend |
| Choosing the Caching backend involves the process of identifying the place where the chart images will be stored after generation. Usually you will select this option if you are in a semi-dynamic environment and want the benefits of improved response times that come through image caching. |

| The CacheToFile Strategy |
Choosing this backend means that caching is enabled. Output is captured and redirected to a file.The validity period of the cached copy can also be specified (in minutes). This means that as long as the validity period is not expired the cached copy will be served. When the cached copy is no longer valid, output is again captured to obtain a fresh copy of the generated image.
