In a perl CGI script, is it possible to throw a 404 error? If so, how is it done?

Read the CGI module docs under "CREATING A STANDARD HTTP HEADER".

Message-Id: <5765cbe5-4cf0-4e47-9529-3be5a96db584@m1g2000yqo.googlegroups.com>
Searched high and low on this and have found absolutely nothing. It's
so bizarre. I've never actually heard of this happening anyway.
(It's Windows, so there's half of the problem there, IMO...)
Running ActiveState Perl v5.10 on Windows XP. All of a sudden, for
seemingly no reason at all (of course none that I know about), I can't
shell out of Perl. For instance:
C:\> perl -e "$dir = `dir`; print $dir;"
Prints nothing. The `dir` doesn't happen. I've tried using qx{} as
well. I have Cygwin running on my machine and it works fine using
Cygwin Perl v5.10. But not under ActiveState. I checked with our
security group and as far as they know, no restrictions are being made
on system() or shell calls on software on our systems. I tried
installing/upgrading to AS Perl v5.12 -- the latest -- but still can't
seem to shell.
Anyone else run into this? It's so bizarre, I can't even conceive of
what would be blocking this.

Do you have either COMSPEC or PERL5SHELL set to something weird in the
environment? Are you attempting to do any of this from a non-standard
terminal emulator (such as 4NT)?
What do you get if you run
perl -le "system 'dir'; print ":$?:${^CHILD_ERROR_NATIVE}:$!:$^E:"
Are you able to run perl under a C-level debugger, and find out what API
calls it's actually making? (Is there a Win32 equivalent of [ks]trace?)

Result is:
:65280:65280:No such file or directory:The filename or extension is
too long:
But $! isn't alwaya reset. I was getting "Bad filename descriptor" at
one point in time. Interestingly, we used similar delimiters for a
similar command I also issued. :-) Freaky how techs think. :-)
I'm still submarined. (Man, I hate Windows, but there's no choice in
the matter here.)

No idea what that means. Soap:Envelope and Soap:Body should be
the first two elements in the request, the method should be within
the Soap:Body element. How is the Web service supposed to know what
method to run, if it's not sent in the request? Maybe the Web Service is
poorly designed? Maybe it's a namespace issue? Who knows...
At least show some of the XML in question.
Show what's expected by the service and what's being sent by
your client.
If the service is in .NET, you have to do more work in Soap::Lite.
Look around the Internet for steps to take.
Also, to help you debug things, you can see what's sent/received,
be enabling trace:
use SOAP::Lite +trace;
If all else fails, you might be able to take the expected XML
request, modify it to suit your needs, and POST it.

Hi All,
I am using use Win32::PerfMon; in a 64 bit windows 7 system. Is htis
module only for 32 bit if so..where can I get a module for 64 bit os.
The module got installed but when running the programme, its showing
the below error. I didn't write any code but just trying to use the
module and see how it works so that I can use it.
"

Basically not able to load the module.
What i want to do:
I want to add c-state residency counter to perfmon and find the c-

Where did you get the module from? Where did you get your Perl from? Are
you sure they're compatible with each other?

Do you have a Win32\PerfMon.dll under either of those directories?

I got the module from cpan. And its their in PPM all available
modules. I installed using PPM.
Yes I have copied perfmon.dll in lib directory.
But is not working still.
Any otherway to find c-stateresidency using perl and command line
option?

Where *exactly* did the PPM come from? Have you added any custom PPM
repositories? Do you have good reason to believe it's a PPM for a 64bit
perl? (Are you actually using a 64bit perl? It's possible to run either
on a Win64 system.)
> Yes I have copied perfmon.dll in lib directory.
*You* have copied it? Where from? Where to, exactly: I presume you didn't
just copy PerfMon.dll directly under one of the lib\ directories? Wasn't
it installed properly by the PPM installer?

Sorry, no idea. I don't use Win32 if I can possibly avoid it.

There's no advantage to HTML, which is also a plain text format.
DocBook would probably be better than HTML, but even it has its
limitations.
Pod can handle images just fine (Learning Perl, Intermediate Perl, and
Mastering Perl were written in Pod and used figures just fine). It's
just that we have almost no images in the core Perl docs. I think we
should have diagrams of more things, especially in the data structures
documentation.

I...
*None* of that was intended as a disparagement of anyone actively
involved in maintaining the Perl docs. I am well aware that it is both a
lot of work and relatively thankless, and I think I've made it clear in
the past that I have little time for people who complain about the
current docs without getting on and fixing the perceived problems.
It goes without saying, but perhaps should be said more often anyway:
thank you for the work you do to improve Perl's docs. It *is*
appreciated.

If your data is not top-secret and you don't mind surrendering control,
Google Charts has a nice interface that you can drive from Perl or

Yes, you are right. There are a few Perl-specific features for
CGI-programming like the taint checking that you mentioned. Those most
certainly belong into a "CGI in Perl" FAQ / document / man-page /
tutorial / .... .
But access rights of the web server do not fall into that category.

OK, I think I understand it more clearly now. I tried to find a newsgroup
specific to CGI but they appear to be inactive. I just thought it would be
helpful to add a topic in the FAQ about where to look for information on
server-side issues and security, since AFAIK perl is the predominate
language used for that purpose. I have requested that the administrator of
my account look at my website files on the server and let me know of any
security issues.
My next step in this project will be to add an activity to the list based on
the data that someone enters in the form provided for that purpose. It
should be sorted by date, and then converted to HTML for the home page to
display. It seems that a server-side script would be best for this purpose,
and Perl may be the best choice, but I might also look into using C or Java
because I am more familiar with the syntax. I might also be able to use
JavaScript in the HTML form submission document to convert to HTML, but I
would still need a server side script to write the file to the server.
I might do some searching for Perl scripts that already do most of what I
need. But I also need to make sure they are well written, which is nearly
impossible for me to determine since the language is still quite foreign to
me. If you can give me some advice as to where I can find what I need, then
I promise I won't bug you guys any more.
Thanks for all you have done so far.
