http get overflow

[guyincognito2 at bk.ru (Guy Incognito)]

Hello framework,

  i have a shellcode problem.
  i need a shellcode for a http get overflow, but as you know there
  are some many bytes not allowed in a http get, that is for me nearly
  impossible to encode my shellcode to avoid this bytes.
  i used the metasploit online demonstration to create a valid
  shellcode but this shellcode is too big.

  can you give me a hint how i can overcome this problem or where i
  can found a good standalone encoder ?

  tnx
