Configure maxHttpHeaderSize

NiskaNivo 2Automatskatomcat

Opis

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.

Očekivani izlaz: compliant
