<Connector URIEncoding="UTF-8" compressableMimeType="text/html,text/plain,text/xml,text/css,text/javascript,image/png,image/gif,image/jpeg,application/json" compression="on" compressionMinSize="20480" connectionTimeout="15000" disableUploadTimeout="true" enableLookups="false" maxHttpHeaderSize="2048" maxThreads="400" minSpareThreads="25" port="8080" redirectPort="8443" server="Service Catalog" useBodyEncodingForURI="false"/>
