[En-Nut-Discussion] File upload via Http

[Lars Andersson]

Hi Vesa, 
I saw your previous posting on this subject, POST method, I also
tried to implement it, but it was to advanced for me, I got lost.
It is very interesting to have the post mechanism, I use GET 
now but need longer strings that post will provide.
Thank you for implementing it.

I am embarrassed to ask, guess I should be able to find out
myself, but how do I "apply patch #1164563 from tracker" ??

Regards,
Lars H. Andersson
