HTTP请求/响应头的平均大小是多少？ [英] What is the average size of an HTTP request/response header?

问题描述

我知道这听起来很愚蠢。

I know this sounds stupid.

我正在使用只有16MB RAM的嵌入式平台。我需要深度数据包过滤HTTP流。为了防止设备的DoS，我想要一些关于HTTP流大小的统计平均值，特别是HTTP标头。

未压缩的请求和响应标头。今天的请求标头大小从大约200字节到大于2KB 。随着应用程序使用更多cookie和用户代理扩展功能，典型的标头大小为700-800字节是常见的。
