I had this same problem, and solved it as follows:
In dojo.js (or whatever), define your JavaScript functions as follows:
if (typeof(DOJOfunction1) == 'undefined')
{
DOJOfunction1 = function(arg1, arg2)
{
// define function 1 here
}
DOJOfunction2 = function(arg1, arg2, arg3)
{
// define function 2 here
}
// etc ...
}
As you can see, you need only one "if undefined" check for all the functions
in dojo.js. If you really want to, you can do a similar trick for each
function independently.
I know that this works for functions, but it might work for variables too (I
didn't have to try that).
Sadly, you're still including dojo.js 5 times, but the 2nd and subsequent
times, the "if undefined" check prevents the functions being included and
parsed more than once.
HTH.
