§Configuring gzip encoding
Play provides a gzip filter that can be used to gzip responses.
§Enabling the gzip filter
To enable the gzip filter, add the filter to
play.filters.enabled += "play.filters.gzip.GzipFilter"
§Configuring the gzip filter
The gzip filter supports a small number of tuning configuration options, which can be configured from
application.conf. To see the available configuration options, see the Play filters
§Controlling which responses are gzipped
You can control which responses are and aren’t gzipped based on their content types via
As a more flexible alternative you can use the
shouldGzip parameter of the gzip filter itself, which accepts a function of a request header and a response header to a boolean.
For example, the code below only gzips HTML responses:
new GzipFilter( shouldGzip = (request, response) => response.body.contentType.exists(_.startsWith("text/html")) )
GzipFilterConfig gzipFilterConfig = new GzipFilterConfig(); GzipFilter gzipFilter = new GzipFilter( gzipFilterConfig.withShouldGzip( (BiFunction<Http.RequestHeader, Result, Object>) (req, res) -> res.body().contentType().orElse("").startsWith("text/html")), materializer);
