.htaccess使用说明 .htaccess可以做大量范围的事情，包括：文件夹密码保护、用户自动重新指向、自定义错误页面、变更你的文件扩展名、屏蔽特定的用户IP地址、只允许特定的IP地址、停止目录表以及使用其他文件作为index文件，等等…… ==Introduction 介绍== 文件名 .htaccess 属性 644 (RW-R–R–) htaccess会影响它所在目录下的所有子目录 注意大多数内容都要求保持在一行之内，不要换行，否则会引起错误 ==Error Documents 错误文档== Official document: ErrorDocument Directive ErrorDocument code document 例子 ErrorDocument 400 /errors/badrequest.html ErrorDocument 404 http://yoursite/errors/notfound.html ErrorDocument 401 “Authorization Required” (注意之后内容如果出现的双引号需要转义为 \”) 常见HTTP状态码 Successful Client Requests 200 OK 201 Created 202 Accepted 203 Non-Authorative Information 204 No Content 205 Reset Content 206 Partial Content Client Request Redirected 300 Multiple Choices 301 Moved Permanently 302 Moved Temporarily 303 See Other 304 Not Modified 305 Use Proxy Client Request Errors 400 Bad Request 401 Authorization Required 402 Payment Required (not used yet) 403 Forbidden 404 Not Found 405 Method Not Allowed 406 Not Acceptable (encoding) 407 Proxy Authentication Required 408 Request Timed Out 409 Conflicting Request 410 Gone 411 Content Length Required 412 Precondition Failed 413 Request Entity Too Long 414 Request URI Too Long 415 Unsupported Media Type Server Errors 500 Internal Server Error 501 Not Implemented 502 Bad Gateway 503 Service Unavailable 504 Gateway Timeout 505 HTTP Version Not Supported ==Password Protection 密码保护== Official document: Authentication, Authorization and Access Control 假设密码文件为.htpasswd AuthUserFile /usr/local/safedir/.htpasswd (这里必须使用全路径名) AuthName EnterPassword AuthType Basic 两种常见验证方式: Require user windix (仅允许用户windix登陆) Require valid-user (所有合法用户都可登陆) Tip: 如何生成密码文件 使用htpasswd命令(apache自带) 第一次生成需要创建密码文件 htpasswd -c .htpasswd user1 之后增加新用户 htpasswd .htpasswd user2 == Enabling SSI Via htaccess 通过htaccess允许SSI(Server Side Including)功能== AddType text/html .shtml AddHandler server-parsed .shtml Options Indexes FollowSymLinks Includes DirectoryIndex index.shtml index.html ==Blocking users by IP 根据IP阻止用户访问== order allow,deny allow from all deny from 123.45.6.7 deny from 12.34.5. (整个C类地址) ==Blocking users/sites by referrer 根据referrer阻止用户/站点访问== 需要mod_rewrite模块 例1. 阻止单一referrer: badsite.com RewriteEngine on # Options +FollowSymlinks RewriteCond %{HTTP_REFERER} badsite\.com [NC] RewriteRule .* - [F] 例2. 阻止多个referrer: badsite1.com, badsite2.com RewriteEngine on # Options +FollowSymlinks RewriteCond %{HTTP_REFERER} badsite1\.com [NC,OR] RewriteCond %{HTTP_REFERER} badsite2\.com RewriteRule .* - [F] [NC] - 大小写不敏感(Case-insensite) [F] - 403 Forbidden 注意以上代码注释掉了”Options +FollowSymlinks”这个语句。如果服务器未在 httpd.conf 的 段落设置 FollowSymLinks, 则需要加上这句，否则会得到”500 Internal Server error”错误。 ==Blocking bad bots and site rippers (aka offline browsers) 阻止坏爬虫和离线浏览器== 需要mod_rewrite模块 坏爬虫? 比如一些抓垃圾email地址的爬虫和不遵守robots.txt的爬虫(如baidu?) 可以根据 HTTP_USER_AGENT 来判断它们 (但是还有更无耻的如”中搜 zhongsou.com”之流把自己的agent设置为 “Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)” 太流氓了，就无能为力了) RewriteEngine On RewriteCond %{HTTP_USER_AGENT} ^BlackWidow [OR] RewriteCond %{HTTP_USER_AGENT} ^Bot\ mailto:craftbot@yahoo.com [OR] RewriteCond %{HTTP_USER_AGENT} ^ChinaClaw [OR] RewriteCond %{HTTP_USER_AGENT} ^Custo [OR] RewriteCond %{HTTP_USER_AGENT} ^DISCo [OR] RewriteCond %{HTTP_USER_AGENT} ^Download\ Demon [OR] RewriteCond %{HTTP_USER_AGENT} ^eCatch [OR] RewriteCond %{HTTP_USER_AGENT} ^EirGrabber [OR] RewriteCond %{HTTP_USER_AGENT} ^EmailSiphon [OR] RewriteCond %{HTTP_USER_AGENT} ^EmailWolf [OR] RewriteCond %{HTTP_USER_AGENT} ^Express\ WebPictures [OR] RewriteCond %{HTTP_USER_AGENT} ^ExtractorPro [OR] RewriteCond %{HTTP_USER_AGENT} ^EyeNetIE [OR] RewriteCond %{HTTP_USER_AGENT} ^FlashGet [OR] RewriteCond %{HTTP_USER_AGENT} ^GetRight [OR] RewriteCond %{HTTP_USER_AGENT} ^GetWeb!

) == Prevent viewing of .htaccess file 防止.htaccess文件被查看== <Files .htaccess> order allow,deny deny from all </Files> == Adding MIME Types 添加 MIME 类型== AddType application/x-shockwave-flash swf Tips: 设置类型为 application/octet-stream 将提示下载 == Preventing hot linking of images and other file types 防盗链== 需要mod_rewrite模块 RewriteEngine on RewriteCond %{HTTP_REFERER} !^$ RewriteCond %{HTTP_REFERER} !^http://(www/\.)?mydomain.com/.*$ [NC] RewriteRule \.(gif|jpg|js|css)$ - [F] 解析: 若 HTTP_REFERER 非空 (来源为其他站点，非直接连接) 并且 若 HTTP_REFERER 非(www.)mydomain.com开头(忽略大小写[NC]) (来源非本站) 对于所有含有 .gif/.jpg/.js/.css 结尾的文件给出 403 Forbidden 错误[F] 也可指定响应，如下例显示替换图片 RewriteRule \.(gif|jpg)$ [R,L] [R] - 转向(Redirect) [L] - 连接(Link) ==Preventing Directory Listing 防止目录列表时显示== IndexIgnore * IndexIgnore *.jpg *.gif Tips: 允许目录列表显示: Options +Indexes 禁止目录列表显示: Options -Indexes 显示提示信息: 页首 文件HEADER, 页尾 文件README ==管理php文件运行方式== 注: 此内容仅适用于运行Hosting Configuration 2.0的Linux共享虚拟主机帐户。你可以在帐户的Hosting Control Center 里的Account Summary 查看你的虚拟主机当前配置。见[http://help.godaddy.com/article/1078 How do I upgrade my hosting account to run Hosting Configuration 2.0?] 来获得更多信息。 默认情况下，带有.php 扩展名的文档在PHP 4下面运行，带有.php5扩展名的文档在PHP 5下面运行。可以用位于你的站点的根部下的.htaccess 文档来更改 这些默认设置。下面某个目录的.htaccess 文档里的条目指定的是.php文档在 PHP 5下面运行，而.php4 文档在PHP4下面运行。 AddHandler x-httpd-php5 .php AddHandler x-httpd-php .php4 对已有.htaccess 文档做的更改立刻即可看到。但是，当创建某个新的.htaccess 文档或者删除某个已有.htaccess 文档时，更改直到htaccess 缓存清除 时才能看到。这种情况每小时都有发生你也可以通过Hosting Control Center 来自动更改你的PHP版本。获得有关此过程的更多信息，见[http://help.godaddy.com/article/3937 Changing Your PHP Language Version.]
