Shouldn't that be ..

print "Content-Type: text/html\n\n"

or does it make a difference?

Also, this is a nit, but it should also print the doc type

<!DOCTYPE HTML PUBLIC "-//W3C/DTD HTML 4.01//EN" 
		"http://www.w3c.org/TR/html4/strict.dtd"> 

for HTML 4 or 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html 
     PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
     "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

for XHTML transitional...

In any event, it might be a good ideas to check your output through the w3c's validator...
http://validator.w3.org/

I realize if you are just experimenting/testing code, then the doc type and validator probably isn't necessary. If it's production code, then I strongly suggest putting in the doc type and validate your output to make it clean HTML or XHTML.
