如果是正常的搜索引擎蜘蛛訪問，不建議對蜘蛛進行禁止，否則網(wǎng)站在百度等搜索引擎中的收錄和排名將會丟失，造成客戶流失等損失�？梢詢�(yōu)先考慮升級虛擬主機型號以獲得更多的流量或升級為云服務器（不限流量）。更多詳情請訪問： http://www.bingfeng168.cn/faq/list.asp?unid=626 

1. 使用網(wǎng)站管理助手環(huán)境：http://www.bingfeng168.cn/faq/list.asp?unid=650 參考此說明啟用設置偽靜態(tài)組件

2.  windows2003+iis手工建站環(huán)境：http://www.bingfeng168.cn/faq/list.asp?unid=639 參考此說明加載偽靜態(tài)組件                 

3.  然后在配置文件中按以下系統(tǒng)規(guī)則配置

Linux下 規(guī)則文件.htaccess(手工創(chuàng)建.htaccess文件到站點根目錄)

<IfModule mod_rewrite.c>
RewriteEngine On
#Block spider
RewriteCond %{HTTP_USER_AGENT}   "Apache-HttpClient|SemrushBot|Webdup|AcoonBot|AhrefsBot|Ezooms|EdisterBot|EC2LinkFinder|jikespider|Purebot|MJ12bot|WangIDSpider|WBSearchBot|Wotbox|xbfMozilla|Yottaa|YandexBot|Jorgee|SWEBot|spbot|TurnitinBot-Agent|mail.RU|curl|perl|Python|Wget|Xenu|ZmEu"   [NC]
RewriteRule !(^robots\.txt$) - [F]
</IfModule>

windows2003下 規(guī)則文件httpd.conf 

#Block spider
RewriteCond %{HTTP_USER_AGENT}   (Apache-HttpClient|SemrushBot|Webdup|AcoonBot|AhrefsBot|Ezooms|EdisterBot|EC2LinkFinder|jikespider|Purebot|MJ12bot|WangIDSpider|WBSearchBot|Wotbox|xbfMozilla|Yottaa|YandexBot|Jorgee|SWEBot|spbot|TurnitinBot-Agent|mail.RU|curl|perl|Python|Wget|Xenu|ZmEu)   [NC]
RewriteRule !(^/robots.txt$) - [F]

windows2008下 web.config

<?xml version="1.0" encoding="UTF-8"?>
  <configuration>
      <system.webServer>
       <rewrite>  
         <rules>         
<rule name="Block spider">
      <match url="(^robots.txt$)"   ignoreCase="false" negate="true" />
      <conditions>
        <add   input="{HTTP_USER_AGENT}"   pattern="Apache-HttpClient|SemrushBot|Webdup|AcoonBot|AhrefsBot|Ezooms|EdisterBot|EC2LinkFinder|jikespider|Purebot|MJ12bot|WangIDSpider|WBSearchBot|Wotbox|xbfMozilla|Yottaa|YandexBot|Jorgee|SWEBot|spbot|TurnitinBot-Agent|curl|perl|Python|Wget|Xenu|ZmEu"   ignoreCase="true" />
      </conditions>
      <action   type="AbortRequest" />
</rule>
        </rules>  
        </rewrite>  
       </system.webServer>
  </configuration>

Nginx對應屏蔽規(guī)則

代碼需添加到對應站點配置文件server段內(nèi)

if ($http_user_agent ~* "Apache-HttpClient|Bytespider|Java|PhantomJS|SemrushBot|Scrapy|Webdup|AcoonBot|AhrefsBot|Ezooms|EdisterBot|EC2LinkFinder|jikespider|Purebot|MJ12bot|WangIDSpider|WBSearchBot|Wotbox|xbfMozilla|Yottaa|YandexBot|Jorgee|SWEBot|spbot|TurnitinBot-Agent|mail.RU|perl|Python|Wget|Xenu|ZmEu|^$"   )
{
  return 444;
}

注：規(guī)則中默認屏蔽部分不明蜘蛛，要屏蔽其他蜘蛛按規(guī)則添加即可
