[Javascript] JavaScritpt simple compression code

[Hakan M (Backbase)]

Eligio, I would go with Matts code here, and if it doesn't work, keep 
pursuing a POST solution. What you are doing now (50+ HTTP GET requests) 
is not a Good Thing. Making the change in the .asp to accept POST 
instead of GET should be a no-brainer, and I can see no reason why GET 
would be more desirable in this situation.

Regards,
H
