[PATCH] http module is not checking correctly HTTP headers

[Jamo <jamofer@gmail.com>]

From: Javier Moragon <jamofer@gmail.com>

I applied the last suggestion in this patch and I've finally realized 
how to use git send-email.

I'm sorry for the unnecesary mails and I hope for next contributions
I won't make the same mistakes, Thank you!
