Lamp--apache prohibit designation of User_agent

User_agent can be used as a browser logo, the current mainstream browser has IE, Chrome, Firefox, 360, the iphone Safari, Android phone Baidu search engine, Google search engine, and so on, each browser has a corresponding User_agent, a few common user_agent are listed below.

mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; trident/4.0;. net4.0c;. net4.0e; SE 2.x)

mozilla/5.0 (Windows NT 5.1) applewebkit/537.36 (khtml,like Gecko) chrome/31.0.1650.63 safari/537.36

mozilla/5.0 (compatible; baiduspider/2.0; +http://www.baidu.com/search/spider.html)

mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; WOW64; trident/4.0; SLCC2;. NET CLR 2.0.50727;. NET CLR 3.5.30729;. NET CLR 3.0.30729; Media Center PC 6.0;. net4.0c;. net4.0e; infopath.3; 360SE)

Make some restrictions on user_agent.

The configuration is as follows:

<ifmodule mod_rewrite.c>

Rewriteengine on

Rewritecond%{http_user_agent} ^*firefox/4.0* [Nc,or]

Rewritecond%{http_user_agent} ^*tomato bot/1.0* [NC]

Rewriterule. *-[F]

</IfModule>

Also use the rewrite module to implement the restriction specified user_agent, in this case, Rewriterule. *-[F] can be directly forbidden to access, Rewritecond with User_agent to match, *firefox/4.0* said, as long as US The er_agent contains firefox/4.0 to match the criteria, where * denotes any character, NC means case insensitive, or indicates or joins the next condition. If you want to limit Baidu's search engine, you can add a rule like this:

Rewritecond%{http_user_agent} ^*baiduspider/2.0* [NC]

Rewriterule. *-[F]

Since there is or OR, it has to be and, as long as you do not write or is and mean.
