Detecting Content-type

[gnubie]

Printing from a Perl CGI program to a web page requires the first printed output to be:

print "Content-type: text/html\n\n";

In some scripts there are several paths to first output and it would be helpful to detect if the Content type has already been output, so redundant Content types could be avoided. Is there a way to detect it?

Thanks,

G

No, not really. Unless you actually have a variable that you set when you print the Content-Type line, there's not much you can do. //Daniel

Like Daniel said, use a boolean and set it to true when you print it out somewhere. Then just check

if ($content_type_printed)

before printing it out again. Sincerely,
