I'm using the following to print HTML to the browser:

my html here

It works fine in IE but when I execute the script under Netscape it displays
the source instead of loading the page based on the source. Please help.

Hi Mariusz,
You need to ensure that you are printing a proper header:
use CGI ':standard';
print header();
print END_HTML;
...
The reason it's working in IE is because someone at Microsoft had the brilliant idea
that when you
someone sends a content type, they might not send the right content type. Rather than
require
people to send the correct data, IE just guesses what the content type should be based
upon the
first few lines of data. Further, even if you forget the extra newline before your
entity-body
and lump the content in with the headers, IE still tries to get things righ.
Unfortunately, this
means that many things work with IE, but appear broken in other Web browsers. The
most common
problem is someone sending the wrong content type for an image, but IE getting it
right and if the
person never tests with other browsers, they don't see that there's a problem.
It also means that if you want to show the source of a Web page, the following will no
longer work
with IE:
use CGI qw':standard';
print header('text/plain');
print 'END_HTML';
!DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.0 Transitional//EN
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd;
html xmlns=http://www.w3.org/1999/xhtml;
head
titleSome Title/title
/head
body
This is the body
/body
/html
END_HTML
Instead, you have to assign the HTML to a variable and then use something like
HTML::Entities to
properly encode it and then print it out as HTML. Many people have been bitten by
Microsoft
deciding to second-guess us. (It's also opened up some nasty security holes).
