Subject Custom status and message: Bug?
Date Mon, 10 Nov 2003 22:26:32 GMT
I have a machine-reading ASP perl script that returns a different status
code for every possible exit point of the program.  Its all part of it
being machine readable.  When its good, its a 2xx number.  When its an
error, its 5xx number.  But not 200 or 500.  This hasn't been a problem,
until today, when I was troubleshooting a problem and found my codes are
being transformed...

versions:

This is perl, v5.8.0 built for i386-linux-thread-multi

package Apache::ASP;
$VERSION = 2.37;

Server version: Apache/1.3.27 (Unix) Debian GNU/Linux

mod_perl debian package - 2.37-3

I present here two files.  One works fine, one doesn't.

--- begin test.cgi ---
#!/usr/bin/perl

print "Status: 213 Woof woof\n";
print "Content-type: text/html\n";
print "CustomHeader: Woof!\n";
print "\n";
print "Woof\n";
--- end test.cgi ---

Don't forget to make that file executable!

--- begin test.asp ---
<%
$Response->{"Status"} = "213 Woof woof";
$Response->{"Content-type"} = "text/html";
$Response->AddHeader("CustomHeader", "Woof!");

$Response->write("Woof\n");
%>
--- end test.asp ---

When I access test.cgi, I get

---
HTTP/1.1 213 Woof woof
Date: Mon, 10 Nov 2003 07:40:51 GMT
Server: Apache/1.3.27 (Unix) Debian GNU/Linux mod_perl/1.27
CustomHeader: Woof!
Transfer-Encoding: chunked
Content-Type: text/html; charset=iso-8859-1

5
Woof

0

And when I access test.asp, I get

---
HTTP/1.1 500 Internal Server Error
Date: Mon, 10 Nov 2003 07:46:00 GMT
Server: Apache/1.3.27 (Unix) Debian GNU/Linux mod_perl/1.27
Set-Cookie: session-id=05e5f34d1d135cb082892941834b5f37; path=/
CustomHeader: Woof!
Content-Length: 5
Cache-Control: private
Content-Type: text/html; charset=iso-8859-1

Woof
---

The Status property of the Response object per the ASP implimentation on
windows IIS takes the whole string '213 Woof woof'.  And outputs it just
like the Status: header in cgi spec.  This is the expected, documented
behavior of the status property on the Response object, to my
understanding.

On the other hand, the Apache::ASP implimentation seems to ignore my
custom message and barf with a 500 error when I try to set it.

Why is Apache::ASP trying to restrict what I can return to the client for
status codes and messages?  What am I missing here?
