Workarounds and Mitigations

Workaround :
System administrators should restrict the permitted maximum size of HTTP request

LimitRequestFieldSize directive,
and Apache Tomcat provides a maxHttpHeaderSize attribute in their respective configuration files). A maximum header value size of 2048 bytes would block all dangerous request.
