Web简介
什么是Web
WWW：World Wide Web，万维网
英国人TimBerners-Lee在1989年欧洲共同体的一个大型科研机构工作时发明的
Web是一种超文本信息系统，其主要实现方式是超文本连接
Web特点
1、Web页面的图形化和易于链接
2、Web与操作系统、浏览器平台无关
3、分布式
4、动态习惯
5、交互性
Web工作原理
HTTP（Hyper Text Transfer Protocol，超文本传输协议）：提供了访问超文本信息的功能，是Web浏览器和Web服务器之间的应用层通信协议
HTTP协议是用于分布式写作超文本信息系统的、通用的、面向对象的协议
Web使用HTTP协议传输各种超文本页面和数据
URL，统一资源标识符：是一个世界通用的负责给万维网上的资源（如网页）定位的系统
静态网站和动态网站的区别
1、静态网站
没有任何程序开发的网站，纯HTML编写；网页文件名是html或htm结尾的
优点：打开速度相对比较快；网站容易被搜索引擎收录；比较安全，重要数据不会丢失
缺点：不能直接对网站内容进行修改，实现不了交互等功能
2、动态网站
通过后台程序，可以方便的对整个网站内容进行修改、删除操作
这些程序都要使用数据库才能完成动态的操作
动态网站的开发语言有：ASP , JSP , PHP , ASP.NET 等
数据库：Access，MySQL，Oracle，SQL Server等
常用组合：
ASP --> Access，MySQL
PHP --> MySQL
JSP --> MySQL，Oracle
优点：维护方便，能实现需要的各种需求；查询信息方便
缺点：要用到数据库，对数据的安全和保密性要求较高；动态网站不利于搜索引擎记录；制作成本较高
Web错误代码
如果出现错误会返回一个表示该请求状态的数字代码，该状态代码记录在Web服务器日志中，同时可以可能在Web浏览器中显示
Web错误代码：
错误代码描述
400错误的请求
401未经授权
403禁止访问：访问被拒绝
404找不到文件或目录
405用户访问该页的HTTP动作未被许可
408请求时间超时
410系统资源已经不存在
411需要内容长度头
412客户端设置的前提条件在Web服务器上评估时失败
413请求实体太大
414请求URL太大
415不支持的媒体类型
500服务器内部错误
501标题值指定的配置没有执行
502Web服务器作为网关或代理服务器时收到无效的响应
503服务不可用
Apache简介
Apache HTTPServer，简称Apache：Apache软件基金会的一个开放源代码的网页服务器
可运行在UNIX、Windows、Linux等系统中
快速、可靠并且可以通过简单的API扩展，将Perl和Python等解释器编译到服务器中
Apache源于NCSA httpd 服务器，经过多次修改发展而成。
特点：简单、速度快、性能稳定、并可以作为代理服务器使用
Apache的特性
支持HTTP/1.1通信协议
拥有简单而强有力的基于文件的配置过程
支持通用网关接口（CGI）
支持基于端口号、IP地址和域名的虚拟主机
支持多种方式的HTTP认证
集成Perl代理模块
支持实时监控服务器状态和定制服务器日志
支持服务器端包含指令（SSI）
支持安全Socket层（SSL）
提供用户会话过程的跟踪
支持FastCGI
通过第三方模块可以支持Java Servlets
