Re: [Dynapi-Dev] DynLayer Bloat

I did alot of research on dynamic compression.  About 90% of the installed
base of Browsers is HTTP 1.1 compliant at this time.  If you use Apache you
can integrate the RCI (Remote Communications Inc) dynamic compression
mod_gzip module (it's free).
http://www.remotecommunications.com/apache/mod_gzip/

Using this you can compress the whole bloated API into a 18K package if you
include EVERYTHING, smarter lads won't.  Size of API isn't my concern.
Optimization is because IE itself is "three-legged dog" slow building
layers.
