Winsock program oppfører seg rart

}

   return 1;
    }

 

Ja folkens, counteren blir altså ikke oppdatert. Har vel noe med at det er et bilde, eller jeg vet ikke. Noen som vet ?

Du kan ikke ha doble newlines mellom ting i headeren. Aka du kan ikke ha \r\n 2x imellom User-Agent,Referer og Connection linjene. Du skal kun ha dobbel \r\n par etter siste header linje, aka etter Connection i din kode.

Og ps: du har jo sagt til srv at connection skal closes etter request, så while loopen din vil ikke fungere.
