I've just added a further line to the head section to force a refresh once every 30secs but I wonder if I've missed something obvious that would allow me to take that line out again as it feels wrong somehow to be doing this. The three relevant lines are currently:-
<META http-equiv="refresh" content="30">
<META HTTP-EQUIV="Pragma" CONTENT="no-cache" />
<META HTTP-EQUIV="Expires" CONTENT="-1" />
Any ideas please?
