How do I find the URL of the .rhtml that's being served?

I have a utility class that’s being used inside a bunch of different
…rhtml files. Is there some sort of global variable that I can use to
figure out exactly what URL is being served? I’m thinking of something
like $PHP_SELF in PHP.

Thanks,

Francis

The server should report this as an environment variable:

try adding $ENV.inspect in your script and look for PATH_INFO,
PATH_TRANSLATED, QUERY_STRING and SCRIPT_NAME

It gives me the path of the file on the server, something like

/home/francis/my_site/cgi-bin/test.rb

Where I really want to see

http://francis.test.com/cgi-bin/test.rb.

I tried Googling around for references of $ENV.inspect, but I didn’t
find anything that made sense to me. (Couldn’t find it in the Pickaxe
book either.) Could you be more specific about how I should do this?

Thanks,

Try this:

http://<%=$ENV[‘SERVER_NAME’]%><%=$ENV[‘REQUEST_URI’]%>

You can see what all the environment variables for a CGI request are
by looking at this webpage:

http://www.aaanime.net/access/env.pl?This_is_the_query_string

That page is written in Perl, but you get about the same environment
variables in Ruby.

This will display all of the enviroment variables available to the CGI
process:

Put inside some page-emitting code …

ENV.each{ |k,v|
print “#{k} = #{v}
\n”
}
