You need to put a hyphen in the 'Content type' word(s) instead of a space. Also, you have a space at the end of the header. I doubt this is part of the problem, but possible. So print "Content type: text/html \n\n"; should say print "Content-type: text/html\n\n";. Oddly, mozilla processes "Content type: text/html \n\n" just fine.
