ATGO_IRewrite.cpp的代码如下：
配置文件只有在运行的时候才会读取，这里提供了正则来用于不用重启IIS来重读配置文件
读取配置文件：
1//初始化配置
2bool ListInit()
3{
4 list<string> listRule;
5 string strBuffer;
6 int i = 0;
7 int len = 0;
8 fstream fsRead;
9
10 //打开文件
11 fsRead.open("C:\\ATGO_IRewrite.ini", ios::in | ios::binary);
12 fsRead.seekg(0, ios::end);
13 len = fsRead.tellg();
14 fsRead.seekg(0, ios::beg);
15 char *buf = new char;
16 buf = '\0';
17 fsRead.read(buf, len);
18
19 //读取文件内容
20 for (i=0; i< len; i++)
21 {
22 if (buf != '\n' && buf != '\r')
23 {
24 strBuffer += buf;
25 }
26 else
27 {
28 if (!strBuffer.empty())
29 {
30 listRule.push_back(strBuffer);
31 }
32 strBuffer = "";
33 }
34 }
35
36 if (!strBuffer.empty())
37 {
38 listRule.push_back(strBuffer);
39 }
40 strBuffer = "";
41 fsRead.close();
42
43 listItem.clear();
44 cmatch match;
45
46 //如果RewriteEngine On则继续
47 if (regex_match((*listRule.begin()).c_str(), match, regexIsOn))
48 {

50
51 list<string>::iterator it = listRule.begin();

56 {

配置文件说明：
RewriteEngine on
RewriteLogger on
RewriteRule .*/(.*)\.atgo /$1.htm
第一行是开启URL重写
第二行是开启日志
第三行是对URL进行正则匹配，Pattern为.*/(.*)\.atgo，如果匹配成功，则转换成/$1.htm
其中$1是前面正则中()的值。
安装说明：
1.把ATGO_IRewrite.ini放到C盘根目录下；
2.把ATGO_IRewrite.dll添加到IIS的ISAPI里；
注:如果是NTFS格式的要设置一下配置文件的权限
3.重启IIS服务。
