/**
 * https://jira.pentaho.com/browse/BACKLOG-22526
 *
 * StrictHttpFirewall was added and made the default HTTPFirewall for FilterChainProxy. As per its javadoc, it is meant
 * to block requests that contains one of the following characters in the URL: period, forward slash, backslash, semicolon, percentage
 *
 * StrictHttpFirewall was added to address 3 different CVEs: CVE-2016-5007, CVE-2016-9879, CVE-2018-1199
 *
 * However, Pentaho's file/folder endpoint resources are passed as path params. And we do support file/folder names with the
 * aforementioned characters. In light of this, we are setting a more lenient HttpFirewall for FilterChainProxy
