#39 Enable gzip compression for served content like application/json

[Anonymous]

To speed up transfer times the html, javascript, css and json responses should be send compressed by the subsonic server. Enabling jetty compression reduced the content to transfer for some rest calls from 400kb to 30kb.

I added the following to the web.xml

<filter>
<filter-name>GzipFilter</filter-name>
<filter-class>org.mortbay.servlet.GzipFilter</filter-class>
<init-param>
    <param-name>mimeTypes</param-name>
    <param-value>text/plain,text/javascript,text/html,text/css,text/xml,text/csv,application/json</param-value>
</init-param>
</filter>
<filter-mapping>
    <filter-name>GzipFilter</filter-name>
    <url-pattern>*</url-pattern>
</filter-mapping>
