this solution has to work flawlessly in production on all 3 desktop
platforms.

I'm giving a shot to modifying LibURL..... I wish I knew why the limit is
in there to begin with, that would help to know if I am wasting my time or
not.

Realistically if it was as easy as just hacking that code, someone would
have done it already.

Its fun anyways....I have to solve this.......even if I speed it up just a
little bit ......

Its not an emergency situation so its a fun problem to think about until
its solved.

some good ideas from you guys.... thanks everyone
