Hi monks!!

As my last nodenewbie questions for web in perl[OT], I've studied Web development these day. After reading a great number of document intensively and hearing some monks' suggestionsRe: newbie questions for web in perl[OT], I decide to make use of CGI::Application to build my web.

It seems all OK so far except one minor thing:

Every page output by CGI will add one line 'Content-Type: text/html; charset=ISO-8859-1'.

yesterday, I ask for it on chatterbox. some guru say there is a redundant statement: header; in my script. But I double check it, the answer is no. Below is my test snippet:

index.html

<!DOCTYPE html
        PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
         "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en-US" xml:lang="en-U
+S">
<head>
<title>login</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1
+" />
</head>
<body>
    <form action = "action.cgi" method = "POST">
        <p> name   <input type = 'text' name = "name" value = "">  </p
+>
        <p> passwd <input type = 'password' name = "password" value = 
+"">   </p>
        <p> <input type = 'submit' name = 'submit' value = "submit">  
+  </p>
    </form>

</body>
</html>

                                                name => $name,
                                        );

Sadly, the wield line is still there!

I suspect my platform (M$ + IIS6.0) caused it without any reasons. Anybody could tell me whether my guess is right or not. I hope perl gurus could enlighten me.

Thanks in advance!!

BTW, I found many questions about CGI on Seekers of Perl Wisdom.(Unfortunately, I can't found the answer to my question) It appears CGI is big, dark and mysterious forest to newbie. ;)

UPDATE

Thanks for everybody replied! I've found use NPH SCRIPTS could solve this question perfectly!

I am trying to improve my English skills, if you see a mistake please feel free to reply or /msg me a correction
