gwan重定向后创建cookie [英] gwan redirection after create cookie

问题描述

对于我的表单验证网页，我想创建一个Cookie，并重定向到另一个网页，但不起作用。重定向阻止创建cookie。你有什么解决方案吗？

For my form validation page, I'd like to create a cookie and be redirected to another page but that doesn't work. Redirection prevents the creation of cookie. Do you have any solution ?

推荐答案

一种方法是从G-WAN处理程序创建cookie，绕过servlet或自动生成的重定向，但您也可以使用此方法：

A way to proceed is to create the cookie from a G-WAN handler, bypassing the servlet or the automatically generated redirection, but you can also use this method:

#include "gwan.h" // G-WAN exported functions

int main(int argc, char *argv[])
{
   char redir[] = "Cookie: blah\r\n" // add a cookie in the response
                  "Location: 100.html\r\n\r\n";
   http_header(HEAD_ADD, redir, sizeof(redir) - 1, argv);

   return 301; // return an HTTP code (301:'Moved')
}
