[ka-Map-users] compressed javascript update

[Paul Spencer]

Chris,

I've just checked this case too:

all js files combined, no white-space/comment removal but with gzip:  
39.7 kb
all js files combined, with white-space/comment removal and gzip:  
20.7 kb

You can try it by adding compress=no to the getcjs.php call.

Am I missing something?

Cheers

Paul
