XML Guestbook - Why relative path?

HI,

I noticed something strange with the xml guestbook. When I wanted to test it in flash itself, i pointed to my server, in other words, i used an absolute path: eg

myXML.load("http://www.blabla.com/guestbook.xml?uniq="+myIdentifier);

same for the php file.

When i did this, the xml just got blanc when submitting messages, even online.

When i use relative paths, like:

myXML.load("guestbook.xml?uniq="+myIdentifier);

and test it online, no troubles though…Could someone explain me why? Maybe stupid question, but it’s the first time I run into something like this :eye:
