apache、iis規(guī)則屏蔽攔截蜘蛛抓取
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。
可以優(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.west.cn/faq/list.asp?unid=626
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} "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$) - [F]
</IfModule>
Windows2008、2012或更高系統(tǒng)下規(guī)則文件web.config (手工創(chuàng)建web.config文件到站點根目錄)
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="Block spider">
<match url="(^robots.txt$)" ignoreCase="false" negate="true" />
<conditions>
<add input="{HTTP_USER_AGENT}" pattern="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" ignoreCase="true" />
</conditions>
<action type="AbortRequest"/>
</rule>
</rules>
