## 15.12. Appendix L: Disabling HTTP Compression

This section provides instructions for disabling HTTP compression in JBoss. This content applies to single-node EKM servers that do not use a front-end webserver, where clients connect directly to the HTTP port of JBoss to access EKM.

For instructions on disabling HTTP compression in a front-end web server, refer to Installing a Front-End Web Server.

HTTP compression is enabled by default in JBoss. It is not necessary under normal circumstances to disable HTTP compression, but if you need to do so, follow these instructions:

1. On each EKM cluster node, stop the EKM server.

2. Edit the JBoss domain configuration (see JBoss Domain Mode and Configuration):

3. Find the `undertow` subsystem element, and find the `server` child element whose `name` attribute value is `default-server`. Find the `host` child element named `default-host`:

       <subsystem xmlns="urn:jboss:domain:undertow:3.0" instance-id="${jboss.server.name}">
         <buffer-cache name="default"/>
             <server name="default-server">
               <host name="default-host" alias="localhost">

4. Under the `host` element, comment out the `filter-ref` child element named `gzipFilter`:

       <!--
       <filter-ref name="gzipFilter"
        predicate="regex[pattern='(?:application/javascript|text/css|text/html)(;.*)?',
        value=%{o,Content-Type}, full-match=true]"/>
       -->

5. Find the `undertow` subsystem element, and find the `filters` child element.

6. Under the `filters` element, comment out the `gzip` child element:

       <!--
       <gzip name="gzipFilter"/>
       -->

7. On each EKM cluster node, start the EKM server.
