I'm confused... why doesn't this work?
#!/usr/bin/perl -wT
print "Content-type: text/html\n\n";
print <<EndOfHTML;
<html><head><title>Test Page</title></head>
<body>
<h2>Hello, world!</h2>
</body></html>
EndOfHTML
If I use multiple print lines instead of the <<EndOfHTML line it works but when I changed it to use the here-document syntax I get an Internal Server Error. I'm sure it's something easy, I just don't know what to look for... a semi colon somewhere maybe?

strange... I rewrote it but changed EndOfHTML to just EndHTML and now it works. Although, I still can't figure out why this works when the other one didn't. Their exactly the same.. arn't they?
#!/usr/bin/perl -wT
print "Content-type: text/html\n\n";
print <<EndHTML;
<html><head><title>Test Page</title></head>
<body>
<h2>Hello, World!</h2>
</body></html>
EndHTML

I figured it out finally...
"When a closing here-document marker is on the last line of the file, be sure you have a line break after the marker. If the end-of-file mark is on the same line as the here-doc marker, you'll get an error when you run your program."
Really, isn't this something they should tell you FIRST? Thanks for the help anyway... I'm sure I'll have more WTF's like this here shortly. :)
