Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi All,

I'm using cgi/perl for the backend processing and its
processing 100,000 records, then the confirmation info
it sends back to the client through html. This program
works fine for few thousand lines processing, but when
user requests for the large file the html page is becoming
blank. How to make sure that the client (html page) waits
while server processing and then the server sends the
appropriate message back to the user (either succeeded
or failed of the processing). btw, all the processing is
being performed properly even with huge data, only the
client side will not be knowing (as the page is blank)
Is there any time delay I need to introduce in html or in
form tag or in cgi ??
Warm Wishes,

Rajeev
