apache环境，使用 .htaccess 文件来设置，复制以下代码添加进去：
RewriteCond%!^$ RewriteRulea/(.*).(php)$–[F] RewriteRuledata/(.*).(php)$–[F] RewriteRuleimages/(.*).(php)$–[F] RewriteRulecss/(.*).(php)$–[F] RewriteRulejs/(.*).(php)$–[F] RewriteRulestyle/(.*).(php)$–[F] RewriteRuleskin/(.*).(php)$–[F] RewriteRuletemplets/(.*).(php|htm)$–[F] RewriteRuleuploads/(.*).(php)$–[F]
windows主机的用户一般都是iis7、iis8环境，将以下代码复制到根目录的web.config 文件：
<rule name="Blocka"stopProcessing="true">
<match url="^a/(.*).php$"/>
<conditions logicalGrouping="MatchAny">
<add input="{USER_AGENT}" pattern="a"/>
<add input="{REMOTE_ADDR}" pattern=""/>
</conditions>
<action type="AbortRequest"/>
</rule>
<rule name="Blockdata" stopProcessing="true">
<match url="^data/(.*).php$"/>
<conditions logicalGrouping="MatchAny">
<add input="{USER_AGENT}" pattern="data"/>
<add input="{REMOTE_ADDR}" pattern=""/>
</conditions>
<action type="AbortRequest"/>
</rule>
#安全设置复制上述代码，修改目录即可！
