Re: mod_perl headers
and I used use CGI::Carp qw(fatalsToBrowser) in my script. It still
didn't print the error to the browser

No. You sent the headers with your send_http_header command. Mason
doesn't have this issue because it waits and builds up the entire
output in a string before it sends any headers out. You can do the
same in your script if you want to.
Take a look at
http://perl.apache.org/docs/1.0/guide/snippets.html#Redirecting_Errors_to_the_Client_Instead_of_error_log
for more info on these issues.
$r->('HI');
That's not a method of $r. Don't do that.

I had $r->print('HI') in my script. I made a typo when typing into
this document.
I know --> I submit the headers but why does it show the headers on
the browser, doesn't
that mean the headers wre submitted twice ?

mod_perl headers
Does Apache submit headers when a error occurs ?
Trying to display an error message to the browser.
I use mason for the web, so if I have die() statement in my code
mason will display the error to the browser.
If I use an Apache handler -> the error doesn't get displayed to the screen,
not sure why. It seems apache submits headers along with my headers when
an error occurs.
