Hi,

I just installed mod_ruby1.2.5 with Apache 2.2.3 on Fedora Core 5
Linux.  Triumphant, I downloaded this test script to my web root
(public_html/test.rbx)

#!/usr/local/bin/ruby
print "HTTP/1.0 200 OK\r\n"
print "Content-type: text/html\r\n\r\n"
print "<html><body>Hello World!</body></html>\r\n"

I restarted my web server but when I load the page in IE, I get

HTTP/1.0 200 OK Content-type: text/html Hello World!

and on Firefox ...

HTTP/1.0 200 OK
Content-type: text/html

<html><body>Hello World!</body></html>

What is wrong?  Below is what I added to my httpd.conf file ...

LoadModule ruby_module /usr/local/apache2/modules/mod_ruby.so
## On Linux (FC3) this becomes
# LoadModule ruby_module /usr/lib/httpd/modules/mod_ruby.so

# ClearModuleList
# AddModule mod_ruby.c

<IfModule mod_ruby.c>
  RubyRequire apache/ruby-run

  # Execute files under /ruby as Ruby scripts
  <Location /ruby>
  SetHandler ruby-object
  RubyHandler Apache::RubyRun.instance
  </Location>

  # Execute *.rbx files as Ruby scripts
  <Files *.rbx>
  SetHandler ruby-object
  RubyHandler Apache::RubyRun.instance
  </Files>
</IfModule>


Thanks, - Dave

It did what you told it to :-) If you do the following, you should see
why:

  telnet 127.0.0.1 80
  GET /test.rbx HTTP/1.0
  Host: localhost
  <hit Enter again>

If I'm right, the web server has already output a HTTP/1.0 response, so
your
script is outputting a second one, which the client sees is not a valid
header, so treats it as the response body.

If you really want your Ruby program to generate the HTTP response,
you'll
need to configure your webserver to run it as an nph script. Maybe
renaming
it to nph-test.rbx will be sufficient. Otherwise just remove the first
print
line from your script.

Regards,

Brian.
