mod_sasl_ssdp/mod_sasl_ssdp.lua @ 5931:d194d1012fd3
Updating dox for mod_rest. Ideas expressed / clarified:
1) Making clear that mod_rest isn't to be installed under VirtualHosts AND as a component.
2) Understanding some of the implications of this choice:
A) Changes to user authentication
B) How it affects subdomains
3) More consistent use of domain names for clarity.
4) Using different heading sizes to show scope of section.
Essentially, I added all the tidbits I had to clarify in getting this to work in my
own example.
