Subject: Re: Large Table
Tim,
The problem is probably not so much the horizontal but the vertical size of
the table. While IE is a bit smarter in that regards, Netscape certainly is
going to choke badly on that one. I think someone said this before, and I
confirm this only: A workaround is to create smaller tables (every 50 or 100
records ) that both browsers can render while more information streams in.
In any event, with an html-file of that size (probably in the scale of
4-5MB ) you actually risk to not only crash the browser (especially older
Netscapes) but even undercapitalized -low memory- computers. Browsers aren't
really designed for that.
About your tempfile:
"...But how do we know when to delete them?"
Well, when the data has changed!

Subject: Re: Large Table
Hey Richard,
Yea thats a solution that we've been currently investigating.
Problem with that is that we dont want the files to just accumulate on the
server so we need a mechanism to delete the files. But how do we know when
to delete them?
Any experience with something like this? I know I could probably just run a
thread and wait a certain amount of time but I really dont want threads
running in my Server.
Thanks,
-Tim

Gin,
Why don't you just have the servlet write the data out as a temporary file
and then return a link to it. You will then be able to close the connection
sooner and possibly compress the data to make the download go faster.

Richard
