Have decided to use HTTrack to mirror sites that are 
curriculum related for use within the classroom. This way 
I can more easily monitor access. By preventing external 
links I can maintain a walled garden of sites. However, 
when a disconnected link is selected I want the browser to 
display the 'Ooops!' html file minus the 'Click here' link 
and then automatically return to the page from whence it 
came. Any suggestions?
