reading pdf/html from ifs send via cgidev2 -- RPG400-L

Just thought you guys would like an update

So far this works the best for returning a pdf from a browser request

(in the real world we will be getting parameters and sending something
meaningful back.  This just illustrates the send back with the immediate
opening of the pdf in a new window)

We call this by putting the following in a browser window

Instead of this would like to try 

'CONTENT-TYPE:  application/pdf'

Fputs above header
Open ifs document
Loop
  Read a buffer 
  Fputs the buffer
Fflush when done   

This would allow us to clean up the ifs right away.  Might also work with
other content types like excel  

What do you think?
