how to change apache product name on header

vi /apache_1.3.X/src/include/httpd.h

หา

#define SERVER_BASEVENDOR “Apache Group”
#define SERVER_BASEPRODUCT “Apache”
#define SERVER_BASEREVISION “1.3.X”
#define SERVER_BASEVERSION SERVER_BASEPRODUCT “/” SERVER_BASEREVISION

#define SERVER_PRODUCT SERVER_BASEPRODUCT
#define SERVER_REVISION SERVER_BASEREVISION
#define SERVER_VERSION SERVER_PRODUCT “/” SERVER_REVISION
enum server_token_type {
SrvTk_MIN, /* eg: Apache/1.3.0 */

SrvTk_FULL, /* eg: Apache/1.3.0 (UNIX) PHP/3.0 FooBar/1.2b */
SrvTk_PRODUCT_ONLY /* eg: Apache */
};

เปลี่ยนเป็น

#define SERVER_BASEVENDOR “Apache Group”
#define SERVER_BASEPRODUCT “Microsoft-IIS” << เปลี่ยนเป็นอะไรก็ได้
#define SERVER_BASEREVISION "6.0" << เปลี่ยนเป็นอะไรก็ได้
#define SERVER_BASEVERSION SERVER_BASEPRODUCT "/" SERVER_BASEREVISION

#define SERVER_PRODUCT SERVER_BASEPRODUCT
#define SERVER_REVISION SERVER_BASEREVISION
#define SERVER_VERSION SERVER_PRODUCT "/" SERVER_REVISION
enum server_token_type {
