Des Perado
We have an elderly DOS-based system running on a Novell Netware server here,
and an extensive intranet. Quite recently the board decided that some
crucial info from the DOS system was to be made available to senior
management via the intranet. After some initial design problems (OK, after
severely scratching our heads at the HOW? question) we were quite pleased
with our solution: a background process in the DOS system gathers the data
and creates four include files, containing not only the stats but also some
of the HTML formatting, then shells to a DOS FTP command to get them to the
web server, and this all happens every 60 seconds. At the client end an ASP
page calls the four includes into a static page and displays the info, with
a meta refresh, also every 60 seconds. It's essential that up to date info
is displayed with one-minute resolution.
This works better than we could have hoped except for one little random
oddity: if a client instance just happens to refresh at the exact
millisecond that the FTP process is taking place we see an ASP 0126 error
and "The include file 'addition.inc' was not found". Hitting F5 reloads the
whole page of course, and we may not see the error again for hours. The
include files are so tiny that the FTP process is over within literally
milliseconds.
It's the last remaining untidiness in the system, and I was wondering if
anybody could suggest a way to avoid the error. I would rather see a blank
portion of the correct web page than a white error screen.
Thanks for reading this.
