apache、iis6、ii7独立ip主机屏蔽拦截蜘蛛抓取（适用vps云主机服务器）

威海Spider 威海Spider

在Apache、IIS6、IIS7独立IP主机上屏蔽拦截蜘蛛抓取的方法如下： 1. Apache服务器：在httpd.conf文件中添加以下代码： ``` SetEnvIfNoCase User-Agent "^Mozilla/5.0\s\(compatible;\sGooglebot/2.1" bad_bot SetEnvIfNoCase User-Agent "^Mediapartners-Google" bad_bot SetEnvIfNoCase User-Agent "^Everflux" bad_bot Order Allow,Deny Allow from all Deny from env=bad_bot ``` 2. IIS6服务器：使用ISAPI_Rewrite插件，创建一个规则，如下： ``` RewriteCond %{HTTP_USER_AGENT} (Googlebot|bingbot|Yahoo! Slurp) [NC] RewriteRule .* - [F,L] ``` 该规则将针对Googlebot、Bingbot和Yahoo! Slurp等蜘蛛用户代理，将其拒绝访问。 3. IIS7服务器：在web.config文件中添加以下代码： ``` ``` 该规则将对Googlebot和Bingbot等蜘蛛用户代理进行拦截，并返回403状态码，拒绝访问。

搜索引擎蜘蛛对于网站抓取是否很智能？如何引导蜘蛛？

尽管搜索引擎在不断的升级算法，但是终究其还是程序，因此我们在布局网站结构的时候要尽可能的让搜索引擎蜘蛛能看的懂。每个搜索引擎蜘蛛都有自己的名字，在抓取网页的时候，都会向网站标明自己的身份。搜索引擎蜘蛛在抓取网页的时候会发送一个请求，这个请求中就有一个字段为User－agent，用于标识此搜索引擎蜘蛛的身份。例如Google搜索引擎蜘蛛的标识为GoogleBot，百度搜索引擎蜘蛛的标识为Baidu

360浏览器模拟百度搜索引擎蜘蛛访问

一般用在网站被挂马以后，直接访问没有问题，可以通过模拟百度或其他搜索引擎来访问，即可发现问题。比如下面的例子，直接访问没问题，使用模拟搜索引擎访问即可发现问题。比如访问一个针对搜索引擎挂马的网页：http://www.zttoten.com/index.php?rmlbgh=cbfmcm&westauditpageinfo=1 [这个地址可能会会失效]，这样就可以看到被挂马的情况。（默认情

3206

抓取策略：那些网页是我们需要去下载的，那些是无需下载的，那些网页是我们优先下载的，定义清楚之后，能节省很多无谓的爬取。更新策略：监控列表页来发现新的页面；定期check 页面是否过期等等。抽取策略：我们应该如何的从网页中抽取我们想要的内容，不仅仅包含最终的目标内容，还有下一步要抓取的url.抓取频率：我们需要合理的去下载一个网站，却又不失效率。让我对“如何和爬虫对话 ”这个课题有了一些思考，下面归
