NAME

Compress::LeadingBlankSpaces - Perl class to compress leading blank spaces in (HTML, JavaScript, etc.) web content.

SYNOPSIS

use Compress::LeadingBlankSpaces;

my $lco_r = LeadingBlankSpaces->new();
. . .
my $source_string = '     some content'."\n";
. . .
my $outgoing_string = $lco_r->squeeze_string ($source_string);
. . .
my $squeeze_status = $lco_r->format_status(); # to check later...

DESCRIPTION

This class provides the functionality for the most simple web content compression.

Basically, the outgoing web content (HTML, JavaScript, etc.) contains a lot of leading blank spaces, because of being structured on development stage. Usually, the client browser ignores leading blank spaces. Indeed, the amount of those blank spaces is significant and could be estimated as 10 to 20 percent of the length of regular web page. We can reduce this part of the web traffic on busy servers with no visible impact on transferred web content. This could be helpful especially for those old browsers which fail to understand the modern content compression.

The main functionality of this class is concentrated within the squeeze_string member function that is supposed to be used inside the data transfer loop on server side. The rest of the class is developed to serve possible exceptions, like pre-formatted data within HTML.

In this version of the class, there are two tags those produce compression exceptions:

<PRE> ... </PRE>

<TEXTAREA> ... </TEXTAREA>

case insensitive in implementation.

EXPORT

None.
