VB6之HTTP服务器的实现(二)

接上篇，这次做了小小的改动和提升。增加了对POST的支持和对其他方法（GET和POST之外的）选择405回复。另外，增加了对CGI的支持，目前可以使用C语言来写（是不是好蠢的赶脚）。相对于上篇，整体做了小小的优化。这次代码就只贴mod_cgi.bas的部分，其他文件我打包了，感兴趣的同学可以下来看看。

注：由于我不是很了解WebServer，写这个东西也是盲人摸象。像什么状态控制、任务调度、容错之类的基本上能省则省，另外也是因为不会写，哈哈。如果有不足之处，还请不吝赐教，右路西裤（霓虹语：请多多指教）！

VB6之HTTP服务器的实现(二)的相关文章

基于JDK7 NIO2的高性能web服务器实践之二（转）

前一篇博客,我简单提了下怎么为NIO2增加TransmitFile支持,文件传送吞吐量是一个性能关注点,此外,并发连接数也是重要的关注点. 不过JDK7中又一次做了简单的实现,不支持同时投递多个AcceptEx请求,只支持一次一个,返回后再投递.这样,客户端连接的接受速度必然大打折扣.不知道为什么sun会做这样的实现,WSASend()/WSAReceive()一次只允许一个还是可以理解,毕竟简化了编程,不用考虑封包乱序问题.也降低了内存耗尽的风险.AcceptEx却没有这样的理由了. 于是再一

[Java聊天室服务器]实战之二 监听类

前言 学习任何一个稍有难度的技术,要对其有充分理性的分析,之后果断做出决定---->也就是人们常说的"多谋善断":本系列虽然涉及的是socket相关的知识,但学习之前,更想和广大程序员分享的是一种心境:学习是一个循序渐进的过程,心态应该随时调节,保持戒骄戒躁的状态.比如最近在看网易公开课MIT<算法导论>,老师提到,学习算法之前要计算机数学+离散数学+概率论等课程的知识,所以一直学不好算法的程序员不妨从基础入手,这都是中国式教育惹的祸啊!(此处省略一万字......)

高效缓存服务器Memcached（二）

一.Memcache 应用一 php与memcache 1.PHP的memcache的客户端 PHP有两个memcache客户端:php memcache和php memcached.php memcache独立用php实现,是老客户端,从我们实践中已发现有多个问题,而且功能少,属性也可设置的少:php memcached是基于原生的c的libmemcached的扩展,更加完善,建议替换为php memcached. 2.PHP memcache的问题 (1).分布式问题 php memcach

高性能web服务器nginx（二）之常用功能举例

一.配置使用nginx 1.提供测试页 [[email protected] ~]# mkdir /www/a.com/htdoc [[email protected] ~]# cat /www/a.com/htdoc/index.html  <h1>www.a.com</h1> [[email protected] ~]# chown -R nginx.nginx /www/a.com/htdoc/ 2.备份配置文件并简要更改配置文件 [[email protected] ~]#

tomcat服务器介绍之二 、session服务器实现方法

上次讲到了session会话的绑定,通过nginx和apache(3种方式)实现 session会话的复制,通过DeltaManager和apache(mod_jk)实现 这次讲解基于msm实现session服务器的过程,需要用到的软件包如下: 一.准备工作,先部署nginx可以反向代理客户端请求至2台tomcat服务器 测试环境在centos7上,使用nginx和tomcat7实现:参考网页 https://code.google.com/p/memcached-session-manager

高性能服务器架构（二）：缓存清理策略

原文链接:https://mp.weixin.qq.com/s/OopSWbLrzT-V11VDZOpxJw 虽然使用缓存思想似乎是一个很简单的事情,但是缓存机制却有一个核心的难点,就是--缓存清理.我们所说的缓存,都是保存一些数据,但是这些数据往往是会变化的,我们要针对这些变化,清理掉保存的"脏"数据,却可能不是那么容易. 首先我们来看看最简单的缓存数据--静态数据.这种数据往往在程序的运行时是不会变化的,比如Web服务器内存中缓存的HTML文件数据,就是这种.事实上,所有的不是由外

Linux基础篇之FTP服务器搭建（二）

上一篇文章说到了搭建FTP匿名用户的访问,接下来讲解一下本地用户的登录. 一.首先先建立一个用户,这里举例:xiaoming,并为其设置密码. 二.修改配置文件. 文件:ftpusers 文件:user_list 文件:vsftpd.conf 三.重新启动服务. 四.测试. 新建目录测试: 这样,本地用户就可以登录FTP服务器. 原文地址:https://www.cnblogs.com/641055499-mozai/p/11577301.html

socket本地模拟服务器+客户端（二）

建立两个py文件,分别打开两个cmd界面,即可进行通信.服务器端运用多进程,连续不断的处理从客户端接收到的数据:客户端通过一个list不断给客户端发送数据. (每个连接都必须创建新线程(或进程)来处理,否则,单线程在处理连接的过程中,无法接受其他客户端的连接.)本例中,多进程其实没有起到作用. 代码以及解释如下: #socket服务器端程序 import socket import time from multiprocessing import Process #多进程和多线程一样的用法 de
