            }
        } 
        
    }
    //apr_file_close(file);
    return OK;
}

static void mergejs_register_hooks(apr_pool_t *p)
{
    ap_hook_handler(mergejs_handler, NULL, NULL, APR_HOOK_MIDDLE);
}

/* Dispatch list for API hooks */
module AP_MODULE_DECLARE_DATA mergejs_module = {
    STANDARD20_MODULE_STUFF, 
    NULL,                  /* create per-dir    config structures */
    NULL,                  /* merge  per-dir    config structures */
    NULL,                  /* create per-server config structures */

    mergejs_register_hooks  /* register hooks                      */
};

二、编译：
1、mod_mergecss.c
   apxs -i -a -c mod_mergecss.c 
编译结果：/usr/lib64/httpd/modules/mod_mergecss.so

1、mod_mergejs.c
   apxs -i -a -c mod_mergejs.c 
编译结果：/usr/lib64/httpd/modules/mod_mergejs.so

三、Apache配置
在Apache配置文件 /etc/httpd/conf/httpd.conf 中
添加：
1、LoadModule mergecss_module    /usr/lib64/httpd/modules/mod_mergecss.so
2、LoadModule mergejs_module     /usr/lib64/httpd/modules/mod_mergejs.so

四、配置请求链接地址
在Apache配置文件 /etc/httpd/conf/httpd.conf 中
添加：
1、
<Location /mergecss>
 setHandler mergecss
</Location>

2、
<Location /mergejs>
 setHandler mergejs
</Location>

五、重启服务器
service httpd restart

六、调用方式：
1、css合并请求  范例：（多个文件用 , 号分隔即可）
http://css.xxxx.com/mergecss?jgdp/reset.css,jgdp/mui.css

2、js合并请求  范例：（多个文件用 , 号分隔即可）
http://js.xxxx.com/mergecss?jgdp/app.js,jgdp/flexible.js

七、大功告成！
