Details

The maxHttpHeaderSize limits the size of the request and response headers defined in bytes.

Rationale:

Limiting the size of the header request can help protect against Denial of Service (DoS) requests.

Solution

Set maxHttpHeaderSize for each connector in $CATALINA_HOME/conf/server.xml to the appropriate setting.

maxHttpHeaderSize=’8192′

Default Value:

By default this is set to 8192.
