Request URI

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hello,

I'm on Windows running IIS using Active State Perl

Since I'm not on apache, does this mean I can't use certain environmental variables?

I'm trying to receive the url the end user is currently requestion, so a little snippet of my code that prints nothing:

my $url = $ENV{REQUEST_URI};
print "$url";  #prints nada!

REQUEST_URI doesn't appear to be part of the CGI specification (though apache does provide it). Try combining SCRIPT_NAME, PATH_INFO, and QUERY_STRING. (as mentioned in rfc 3050). "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply]

I have seen a few tutorials on Environment Variables in Perl that show REQUEST_URI as a perl Environment Variable. They dont say anything about apache providing it and IIS not. I'm not saying Joost is wrong, but there may be some tutorials out there that are.	[reply]

the environment variables for a cgi program are always set by the webserver running the code. otherwise, how would they get set? REQUEST_URI is nice to have but since it's not in the CGI specs webservers are not under any obligation to provide it. Also the MS support page "Environment Variables Returned by IIS via CGI" doesn't list REQUEST_URI either. "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply]

Try this: `my $url = $ENV{'REQUEST_URI'}; print "$url";` [download] Update: Oops.. I'm sorry, I was thinking in terms of Linux. Maybe Win32::Env could help.	[reply] [d/l]

As Joost suggested, you may have to build it from other environment vars. To get a list of all the environment vars your install of IIS provides to perl, you could dump the `%ENV` hash to a file like so: `#!c:/perl/bin/perl -w use strict; use Data::Dumper; open my $ENV_DUMP, '>', 'c:/iis_env.txt' or die $!; print {$ENV_DUMP} Dumper(\%ENV); close $ENV_DUMP; print "Content-Type: text/plain\n\nSuccess!";` [download] Of course, you want to run this through IIS, not the Windows command line. __________ Systems development is like banging your head against a wall... It's usually very painful, but if you're persistent, you'll get through it.	[reply] [d/l] [select]
