newbie question about print header

I want to know how to tell my application not to cache. Kevin Meltzer's book and Lincoln Stein's book neatly drop that ball between them. Can I use the cgi.pm header routine and hand it a variable? print header (-no-cache= 1) .. there are several variants of this --- using -nph-1 its

Re: newbie question about print header

From the CGI.pm docs... Most browsers will not cache the output from CGI scripts. Every time the browser reloads the page, the script is invoked anew. You can change this behavior with the -expires parameter. When you specify an absolute or relative expiration interval with this parameter,

Re: multistring replacement

That's one way to pass the file content to a script via the STDIN filehandle. A shorter way is to pass the filename to the script: $ ./myscript file.html Try out this code: #!/usr/bin/perl use strict; use warnings; open my $fh, $ARGV[0] or die can't open passed file '$ARGV[0]': $!;

counting scalar array elements question

Hi all, I have an array question: If I have a variable, $var, and it contains an array how would I be able to easily count the number of elements in the array? I've tried creating a new array and pushing the original array on to it but that creates an array of arrays. Basically I have: my

You need to dereference your array ref. my $count = @{$var}; Or in some circumstances it might make more sense to explicitly use scalar context: my $count = scalar @{$var}; -Original Message- From: Graeme McLaren [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 08, 2006 3:57 PM
