comment What does “incoming” and “outgoing” traffic mean?
@MichaelHampton sorry, didn't mean to digress, it seems I misunderstood @Hex's comment and I wanted a clarification. From my understanding now, outgoing rules refer to the destination port - so if the client originated the request on its port X (its source port) the server must accept outgoing traffic to X to be able to send a response (automatically - as you said - or not, but it must allow). Did I get it right now? (if so, the answer to my last comment would be: the destination port)

comment What does “incoming” and “outgoing” traffic mean?
The expression "outgoing web service traffic" came from this. In my particular case, I'm trying to set up the firewall in a server instance (IBM cloud). The default install came with most things blocked (I could run Apache but not access it from outside), and I'd like to know the miminal things I should unblock to be able to serve pages, receive file uploads (from the client's browser), etc. And I couldn't tell if that particular piece applied to my case or not - since it only tells how, not why.

comment What does “incoming” and “outgoing” traffic mean?
So, my web server should unblock incoming connections on ports 80 and 433, does not need to worry about outgoing connections on those ports, but need to allow outgoing connection in the dynamic/ephemeral port range, is that right? And I'm still a bit confused with the outgoing thing: if a web client tries to connect to a site, the destination port would be 80, but the source port could be anyone. Which port would a firewall in that machine consider when deciding to block/unblock?

comment mod_wsgi only working when user is logged in
@Banjer posted. There's nothing unusual in it as far as I can tell, and I've used a similar setup in windows machines with no issues. I've already solved most permission denied problems (all relevant files are 755), and this error only occurs when I'm not currently logged in with myuser.
