This could have issues :
Could you explain this again please!
(1). Session time out issue will come into the picutre again.
(2). the pipe stream you are talking is for client-server based or
for web based? open another socket connnection to pipe for the file
not http connection?
(3). disk file is kind of cache tech, if any exception occured,
data lost
Thanks
Larry

Larry,
use sax, pipe the input stream from the network connection strait into sax,
you don't need to hit the disk and you don't need to
create a big string to parse things in memory. I've done it before and I'll
do it again.
-Peace
Dave
