2 questions about " Spark client secure audio/video with Red5 plugin "

Hello,

I’ve tried the document

Spark client secure audio/video with Red5 plugin

but I got some trouble on my site so I got 2 question about it.
First: How do allpy the fix to the apache? Is it what I have to add to the httpd.conf and what do I have to delete then from the original one? (I’m using the apache from the xampp package)

Second: It says that I have to have a trusted SSL certificate.

Does that count for Openfire or apache (or both?)

Thanks in advance,

maddi
