Response header name ' Content- type' contains invalid characters, after running a Perl_CGI script.
Hello ! Everyone, I am back here again to get your help.
Sorry, sorry for getting help alone and not helping other people's post.
But I will try to help others in another way, so please generous.
O.K. let me get started. I got weird error message as shown at the title, while I am reviewing the error_log at /var/log/httpd/ error_log. I never encountered this error message, so I can't figure the point of the error message. Does anyone has any clue to fix this error?
I will post the references.

Hello ! Everyone. I just got fixed the problem right now. There is a BLANK (white space) in front of ' Content-type ...' like this, that resulted the httpd error mentioned above.
So stupid to myself. But this is the daily life of not-so-bright programmer. Thanks so much !!
I posted another CODE, the CODE which caused the above mentioned error is here below.
=== CODE ======
# BEGINNING of cgi52_search_header_us01.pl
#
print " Content-type: text/html\n\n" ;
print "
Search Result of $query_performer_name.
" ;
print "
$query_performer_name
";
# Here is border line ===========================================================
Sorry I can't add a good posting of HTML tag containing CODE, but it was becuase of cgi52_search_header_us01.pl, not because of cgi53_search_header_us01.pl. And in cgi52_xxx there was a BLANK (white space) like print " Content-type: text/html\n\n" ;
Thanks.
Sometimes just explaining a problem you can't figure out enables you to figure it out. Strange, but true.
I would note that posting something like this on https://stackoverflow.com/ and tagging it with #perl will get you helpful feedback quite quickly.
