What did I do wrong?

I'm pretty sure I copied Firefox's output correctly.



#!/bin/sh



POSTID=1355016238

NAME=%20

EMAIL=sage

COMMENT=%20%0D%0A



STR="bbs=prog&id=$POSTID&shii[spoiler]t[/spoiler]chan=pro[u]p[/u]er2&kot[b]e[/b]han=$NAME&me[i]i[/i]ru=$EMAIL&com=$COMMENT&email=%27"

STRLEN="$(echo \"$STR\" | wc -c)"

STRLEN=88

{

    echo -n "POST /post HTTP/1.1\r\n"

    echo -n "Host: dis.4chan.org:80\r\n"

#    echo -n "User-Agent: netcat\r\n"

    echo -n "Referer: http://dis.4chan.org/read/prog/$;POSTID\r\n"

    echo -n "Content-Type: application/x-www-form-urlencoded\r\n"

    echo -n "Content-Length: $STRLEN\r\n"

    echo -n "\r\n"

    echo -n "$STR\r\n"

} | nc dis.4chan.org 80

Yes, I am fully aware this is pathetic.

On the Referer, the semicolon was not present in the original code.

I already knew it would transmute shii[]chan=proper[]2 to lol wut, but it outright rejected my post for containing all of the POST variables.

I had to obfuscate them somehow, and that was the first thing that came to mind.
