Dynamic HTML size

[mszigetvari]

Hi

Generating dynamic HTML via CGI script
(for example a file list)
I would like to send an alert if the size is greater as some limit

[gits]

could you please explain your issue in more detail so that a reader could follow it? and what do you have done so far to solve the problem?

Hi

A CGI script is generating the HTML page , as reading a file and put out the content into a dynamic HTML page. If the file size is greater as a limit, I would like to send an alert or some other kind of notification and stop the HTML generation .

then i would suggest that the CGI script checks the filesize first - if the input-file is less then the limit then fine - otherwise it creates another output with your mentioned notice. this could even include the generation of JavaScript code into the page.

Hi

Unfortunatly I can determine the file size only if I read in. The server is running on a mainframe z/OS system .

uhhh ... i'm not familiar with such ... but if this is the case then you even read it in - determine the size and then decide which output is to be generated. looks like overhead of course, and it is - but i can't say whether or how to determine filesize if something like this fails:

#!/usr/bin/perl -w
 
$filename = '/path/to/your/file.ext';
$filesize = -s $filename;

PS: such a question might be answered better in the PERL forum then

Hi

I hoped to put out some fancy message on the top of the HTML page, if I notice at the end of the HTML page, that the input is too large
