Re^3: Inconsistent Perl code in Internet Explorer 8

This code was done by a friend, but he insists that there is nothing wrong,

Well, aside from the notes by JavaFan, the code is broken. It makes assumptions about the value of $data, and the big mistake, it trusts the user not to be malicious. The value of $data can vary from browser to browser. My first link and the links it links, deal with this in some detail. Read it.

By the way, how does code printing headers looks like?

Read my links, there are at least 3 examples, and they all contain the word "header"

This example prints a header, and doesn't include the word "header": `print "Content-Type: text/html\r\n\r\n";`	[reply] [d/l]

And your point is? Premature end of script headers/Malformed script headers messages. followed immediately print `print "Content-type: text/html\n\n";` [download] Did you output a valid CGI header first? followed immediately by `print "Content-type: text/plain\n\n";` [download] You know tobyink, you really can be bored sometimes :)	[reply] [d/l] [select]
