Avoid a network error with iCal and a local WebDAV server
Authored by: funkyone on Mar 09, '07 01:08:25PM
Actually, it doesn't matter if 127.0.0.1 or 127.0.0.0 is used. All adresses between 127.0.0.0 and 127.255.255.255 are loopback adresses. Although usually 127.0.0.1 is used, according to RFC 1700 (http://tools.ietf.org/html/rfc1700) all adresses stat start with 127 refer to the same computer and should never allowed "escape" onto the actual network by the TCP/IP-Stack.

What disturbs me more is that the WebDAV-Server returns an error upon loopback access via the external IP. Is that some kind of security feature? It makes not much sense to me.
