Subject: Added function to serve requests from any frontend
X-Git-Url: http://git.cascardo.eti.br/?p=cascardo%2Fatompub.git;a=commitdiff_plain;h=a31ac2babb967583a167889fab9b6cfdb25905de

Added function to serve requests from any frontend

This function serves requests from any frontend. This would be common
code among all frontends. That's why implementing in the core makes more
sense.
