I don't have root access, so naturally (nsv 80) gives "listen on 80 failed (Permission denied..." error.
Apache is up, but I'm not sure what I can do with it. Is there a simple redirect I need to run?
To be precise, I've loaded arc2 into a directory [mydomain]/news corresponding to news.[mydomain].com, with the news.arc specifying "news.[mydomain].com" as the site url; I launch the Arc REPL from there ("mzscheme -m -f as.scm") and do "(nsv)"... to no avail.
Try accessing news.[mydomain].com:8080. If you have some sort of terminal access on your remote computer, try lynx http://news.mydomain.com:8080/
As for the Apache <-> Arc talking thing, you'll have to wait for someone else to answer that question; I honestly don't know, because I haven't deployed one yet.
