[Java Web] Error parsing HTTP request Header Note:further occurrences of HTTP header parsing errors

Tomcat throws an error when the Mobile client submits an HTTP request to the server:

December 31, 2014 2:32:45 pm Org.apache.coyote.http11.AbstractHttp11Processor Process
Info: Error parsing HTTP Request Header
Note:further occurrences of HTTP header parsing errors'll be logged at DEBUG level.

After debugging, it is found that Tomcat's header buffer size is not enough, only need to add the Maxhttpheadersize field in Server.xml:

<connector uriencoding= "UTF-8" port= "8080" protocol= "Org.apache.coyote.http11.Http11NioProtocol" Usebodyencodingforuri= "false" enablelookups= "false"               connectiontimeout= "20000"               redirectport= "8443" Maxhttpheadersize= "The size you want"/>

However, this problem does not occur with Web submissions, even if the phone repeatedly emphasizes the use of post, and is still suspected because the use of the get causes the header data to be too long.
