HTTP Continuation or non-HTTP traffic

发现一个 HTTP      Continuation or non-HTTP traffic的数据包，之前没有碰到过。不懂其意义，一看长度，显示1460，与TCP segment of a reassembled PDU有点类似，对于这个字段的意义，GOOGLE了一会，发现有如下的解释：

That means ethereal sees packets on tcp port 80 which don't contain an http header. This is quite common, since many http-objects are larger than 1 tcp packet. Hence the comment "Continuation". You can probably see an http-packet before those "continuations".

It also means you have some re-assembly settings turned off. Either the "reassemble http headers" and "reassemble http bodies" options are turned off in the http protocol preferences and/or the "allow subdissector to reassemble tcp streams" option is turned off in the tcp protocol preferences. 

If they were all turned on, you would have seen "tcp segment of a eassembled PDU" frames, ending in a http frame, containing the 
whole http-request or http-response.
