Safari backtracking trouble

Isn't it funny (haha!) that Apple's own browser does not care about  
what is written in the Apple docs about backtracking (http:// 
developer.apple.com/documentation/WebObjects/Web_Applications/ 
Articles/8_Backtracking.html). Safari gives a damn about all the  
headers that are set. So far things have worked fine for my anyway  
but now the backtracking problem bit me hard:

I've got a webapp that allows the users to browse through a file  
tree. When the users change from one directory to an other and then  
use the back-button to return, they're in trouble on the next  
click... when using Safari. Of course things work fine with Firefox.

Since no request is sent to the webapp I cannot intervene at this  
point. Only when the user clicks on the next link, a request is sent  
to my component for a link that the component does not seem to know  
anything about it anymore.

I've read all that Apple has to say about backtracking and also had a  
look at one approach that is published on wocode.com but maybe  
someone has a good general solution...?
