Configure maxHttpHeaderSize

RendahLevel 2Otomatistomcat

Deskripsi

The maxHttpHeaderSize limits the size of the request and response headers defined in bytes. No Connector may raise maxHttpHeaderSize above 8192 bytes (unset means the default 8192). Reads $CATALINA_BASE (default /opt/tomcat) and $CATALINA_HOME (default: $CATALINA_BASE); set them for packaged installs (e.g. CATALINA_BASE=/var/lib/tomcat10, CATALINA_HOME=/usr/share/tomcat10). XML comments are ignored.

B=${CATALINA_BASE:-/opt/tomcat}; H=${CATALINA_HOME:-$B}; O=${TOMCAT_OWNER:-tomcat_admin}; G=${TOMCAT_GROUP:-tomcat}; x(){ [ -r "$1" ] || return 1; awk 'BEGIN{RS="<!--"} NR==1{print;next} {i=index($0,"-->"); if(i) print substr($0,i+3)}' "$1" | tr '\n\t\r' '   ' | tr '<' '\n'; }; s=$(x "$B/conf/server.xml") || exit 1; printf '%s\n' "$s" | awk 'function at(n,  r){if(match($0,"[[:space:]]" n "[[:space:]]*=[[:space:]]*[\"\047][^\"\047]*")){r=substr($0,RSTART,RLENGTH); sub(/^[^=]*=[[:space:]]*./,"",r); return r} return "-unset-"} /^Connector[[:space:]]/{v=at("maxHttpHeaderSize"); if(v!="-unset-" && (v+0<1 || v+0>8192)) bad=1} END{print bad?"noncompliant":"compliant"}'

Output yang diharapkan: compliant
