You Cheated, the Code Does Not Work

The resets are going to the wrong place!
The 2 flag to rewrite is new
You can use a BPF filter to swap src and dst
Install it on the call chain
Call it "src_dst_swap"
Call prior to calling rewrite.

Syntax errors on ipdata lines!
Strings as number is not yet implemented
Translate the string to hex
Use 0x47455420 instead of "GET "
