Re: Why won't scipts on an Apache server not show up when viewed with Netscape. by turnstep (Parson) on May 03, 2000 at 04:42 UTC
Sometimes, Netscape will not show anything (e.g. unclosed table tags are a good place to start your search), but View->Source will. Strange but true - and a good way to debug.	[reply]

What is showing up, then? Are you sure you're sending back the correct HTTP header? Make sure you're sending back a Content-Type of text/html: `use CGI qw/:standard/; print header;` [download] Or, if you're using mod_perl: `$r->content_type("text/html"); $r->send_http_header;` [download]	[reply] [d/l] [select]
