Gateway Interface 3.7 Status Codes Status codes are used by the HTTP protocol to communicate the status of a request. For example, if a document does cgi script error not exist, the server returns a "404" status code to the browser. If cgi error 500 a document has been moved, a "301" status code is returned. CGI programs can send status information as part of a

virtual document. Here's an arbitrary example that returns success if the remote host name is bu.edu, and failure otherwise: #!/usr/local/bin/perl $remote_host = $ENV{'REMOTE_HOST'}; print "Content-type: text/plain", "\n"; if ($remote_host eq "bu.edu") { print "Status:

200 OK", "\n\n"; print "Great! You are from Boston University!", "\n"; } else { print "Status: 400 Bad Request", "\n\n"; print "Sorry! You need to access this from Boston University!", "\n"; } exit (0); The Status header consists of a three-digit numerical status code, followed by a string representing the code. A status value of 200 indicates success, while a value of 400 constitutes a bad request. In addition cgi error log to these two, there are numerous other status codes you can use for a variety of situations, ranging from an unauthorized or forbidden request to internal system errors. Table 3.3 shows a list of some of commonly used status codes. Table 3.3: HTTP Status Codes Status Code Message 200 Success 204 No Response 301 Document Moved 401 Unauthorized 403 Forbidden 404 Not Found 500 Internal Server Error 501 Not Implemented For a complete listing of status codes, see: http://www.w3.org/hypertext/WWW/Protocols/HTTP/HTRESP.html Unfortunately, most browsers do not support all of them. The "No Response" Code One status code that deserves special attention is status code 204, which produces a "no response." In other words, the browser will not load a new page if your CGI program returns a status code of 204: #!/usr/local/bin/perl print "Content-type: text/plain", "\n"; print "Status: 204 No Response", "\n\n"; print "You should not see this message. If you do, your browser does", "\n"; print "not implement status codes correctly.", "\n"; exit (0); The "no response" status code can be used when dealing with forms or imagemaps. For example, if the user enters an invalid value in one of the fields in a form or clicks in an unassigned section of an imagemap,

Unfortunately it is still returning a 200 Status OK when using POST or PUT. my ($buffer); # Read in text $ENV{'REQUEST_METHOD'} =~ tr/a-z/A-Z/; if ($ENV{'REQUEST_METHOD'} eq "GET") { $buffer = $ENV{'QUERY_STRING'}; } else { $cgi->$header->status('405 Method Not Allowed') print $cgi->header('text/plain'); } I am still new to CGI programming so I figured someone here http://stackoverflow.com/questions/19872574/perl-cgi-with-http-status-codes could toss me a bone about working with CGI and HTTP status returns. If a good CGI doc is provided that would be awesome, as most returned by search are CPAN (already read a few times) and really old tutorials that are not Object oriented. perl http cgi w3c share|improve this question asked Nov 9 '13 at 5:07 MattSizzle 2,2601035 add a comment| 1 Answer 1 active oldest votes up vote 4 down vote accepted cpan docs is more than enought for CGI. If you want new tutorials don't use CGI, use one of MVC frameworks ( Catalyst, Dancer2, Mojo, etc ). You can post 405 header if will change: $cgi->$header->status('405 Method Not Allowed'); print $cgi->header('text/plain'); to this: print $cgi->header( -type=>'text/plain', -status=> '405 Method Not Allowed' ); share|improve this answer answered Nov 9 '13 at 6:39 Suic 1,7891824 I did not want to use Catalyst or Dancer as this is for a tiny Restful service, but I have looked into mojo and I want to use it next time I build a full blown website as it looks very promising. Thank you for the answer. –MattSizzle Nov 9 '13 at 20:08 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up usi

The RFC Editor has chosen to publish this document at its discretion. Readers of this document should exercise caution in evaluating its value for implementation and deployment. Abstract The Common Gateway Interface (CGI) is a simple interface for running external programs, software or gateways under an information server in a platform-independent manner. Currently, the supported information servers are HTTP servers. The interface has been in use by the World-Wide cgi error Web (WWW) since 1993. This specification defines the 'current practice' parameters of the 'CGI/1.1' interface developed and documented at the U.S. National Centre for Supercomputing Applications. This document also defines the use of the CGI/1.1 interface on UNIX(R) and other, similar systems. Robinson & Coar Informational [Page 1] RFC 3875 CGI Version 1.1 October 2004 Table of Contents 1.

Configuring Apache to permit CGI Writing a CGI program But it's still not working! What's going on behind the scenes? CGI modules/libraries For more information See alsoComments Introduction Related ModulesRelated Directivesmod_aliasmod_cgimod_cgidAddHandlerOptionsScriptAlias The CGI (Common Gateway Interface) defines a way for a web server to interact with external content-generating programs, which are often referred to as CGI programs or CGI scripts. It is the simplest, and most common, way to put dynamic content on your web site. This document will be an introduction to setting up CGI on your Apache web server, and getting started writing CGI programs. Configuring Apache to permit CGI In order to get your CGI programs to work properly, you'll need to have Apache configured to permit CGI execution. There are several ways to do this. Note: If Apache has been built with shared module support you need to ensure that the module is loaded; in your httpd.conf you need to make sure the LoadModule directive has not been commented out. A correctly configured directive may look like this: LoadModule cgid_module modules/mod_cgid.so On Windows, or using a non-threaded MPM like prefork, A correctly configured directive may look like this: LoadModule cgi_module modules/mod_cgi.so ScriptAlias The ScriptAlias directive tells Apache that a particular directory is set aside for CGI programs. Apache will assume that every file in this directory is a CGI program, and will attempt to execute it, when that particular resource is requested by a client. The
