Hey Will, I do indeed think that this patch is useful and I would like to apply it to my configuration! Alas I am not all that good with the modification/patching of programs using the source code (I only know how to program in Visual Basic... which I am hoping to ditch and learn C++) or the use of linux in general for that matter. Therefore I ask could you, or anyone else please provide information or a reference to information regarding how to implement such a patch on linux for apache. I'm sorry if I'm asking a stupid question but if someone could push me in the right direction it would be greatly appreciated. thanks, Jason.
