Re: [squid-users] Redirect not working with images

The program need to loop, reading lines and write back the new URL.. and
you MUST disable stdio buffering, or else your c-library will buffer the
printf, and it is never sent to Squid..

Further, URL's can be a lot longer than only 1024 characters...

#include <stdio.h>

#define SIZE 8192
main()
{
    char buf[SIZE];
    setbuf(stdout, NULL);
    while(fgets(buf, SIZE, stdin)) {
        printf("%s", buf);
    }
}
