Ok, let's say we have a main flash movie and we are loading external movie clips as new "pages." In this example my main movie is called
master.swf and my external movies are called page2.swf and page3.swf. Your files can be called whatever you want.
The following code should live on frame 1 of your externally loaded movie (let's say it's page2.swf).
//set a new entry in the history object
_level0.referrer = "page2";
//if previous page is not this page then add to array
if (_level0.history[_level0.history.length-1] != _level0.referrer){
_level0.history.push(_level0.referrer);
}
The code above just adds to the array - it looks at the last page we were at and if it is not the page we just navigated to, it adds that entry.
Maybe you have some global navigation, if the user went to the link for page 2 three times in a row, that would add three entries to the array. The
above code prevents this.
