==== Gzip Rules
`GzipHandler` will gzip or deflate the content of a response if:
`GzipHandler` will gzip the content of a response if:
* It is mapped to a matching path
* The request method is configured to support gzip
* The request is not from an excluded User-Agent
* accept-encoding header is set to either gzip, deflate or a combination of those
* accept-encoding header is set to gzip
* The response status code is >=200 and <300
* The content length is unknown or more than the minGzipSize initParameter or the minGzipSize is 0(default)
* The content-type does not match an excluded mime-type
* No content-encoding is specified by the resource
If both gzip and deflate are specified in the accept-encoding header, then gzip will be used.
Compressing the content can greatly improve the network bandwidth usage, but at the cost of memory and CPU cycles.
The link:#default-servlet[DefaultServlet] is capable of serving pre-compressed static content, which saves memory and CPU.
By default, the `GzipHandler` will check to see if pre-compressed content exists, and pass the request through to be handled by the `DefaultServlet`.
