[ka-Map-users] gzip-ing .js

[Paul Spencer]

Brent,

thanks for this.  I've added it to ka-Map's getcjs.php function as  
per my earlier post.  This results in a significant reduction in file  
size ... from 170kb to about 22kb.  Just removing whitespace and  
comments is about a factor of 2 improvement (170 to 88kb) then  
gzipping reduces by a factor of 4!

Cheers

Paul
