From: ccgreg@gold.missouri.edu (Greg Johnson ) Date: 21 Jun 1996 18:33:38 GMT Newsgroups: comp.infosystems.www.authoring.cgi This is sort of covered by Tom's points, but I've phrased it explicitly in showing a model CGI script to Learners of Perl: # The First Thing to do in any Perl CGI Script: open(STDERR,'>&STDOUT'); $| = 1; # This causes error messages to display with # standard output, as soon as they occur. # Otherwise CGI run-time errors don't display. # The Second Thing to do in any Perl CGI Script: print "Content-type: text/html\n\n"; # Every browser expects a header like this one. # If we delayed sending this, and we generate an # error, this error message would be the first # thing to print--as a "malformed header". # Now we can do our intended tasks. The whole example's in: http://www.phlab.missouri.edu/perl/demo/
