原因：

据说是Apache tomcat6的一个bug,需要增加maxHttpHeaderSize来处理。

tomcat的HttpHeaderSize默认值为8192,而你请求时超过了这个范围,可以修改这个这值已适应你的需求

解決方法：

Tomcat或JBoss的server.xml打开

指定maxHttpHeaderSize="8192"

<Connector port="8080" address="${jboss.bind.address}" maxThreads="250" maxHttpHeaderSize="8192"  

    emptySessionPath="true" protocol="HTTP/1.1"  

    enableLookups="false" redirectPort="8443" acceptCount="100"  

    connectionTimeout="20000" disableUploadTimeout="true" />  

例如：将maxHttpHeaderSize的值修改为:maxHttpHeaderSize="81920"

注意：

在AJP连接的场合,

不应使用maxHttpHeaderSize，而是指定packetSize。

<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" packetSize="81920"  

maxThreads="150" scheme="https" secure="true"  

clientAuth="false" sslProtocol="TLS" />
