eRuby questions

[Dude]

Hi,

I have been trying to find alternatives and faster way of serving
server side HTML or WML from Ruby instead of serving it through an ERB
program or through a RAILS program.

This question is somewhat related to an earlier question posted by
Sunny Hirai.

I have begun evaluating eRuby and configured it with Apache on a
Windows Machine.

Basic ruby output seems to be working fine, but whenever I try use CGI
methods to read request parameters or create cookies, an internal
server 500 is being thrown.

Can anyone tell me,

If anyone has configured and used eRuby for serving dynamic WEB / WML
pages
Are there standard bench marks to see the performance difference
between RAILS vs ERB vs eRuby vs ERUBIS and which is the best
recommended ?

Erubis claims to be fastest eRuby implementation. Never seen any
dispute about it.

Do you mean Apache with mod_ruby, or some other way?

http://wiki.modruby.net/en/?InstallGuide (but I'm not sure mod_ruby runs
under Windows)

What is written to your Apache error log?

None of the CGI methods seem to work with eRuby.

And no, I have not configured mod_ruby - I have only directly
configured eRuby.

Is your eRuby emitting the HTTP response headers or just the body text?

The latter won't do I think.

Hi, Dude!
Are you sure you haven't forgotten the quotes:

require 'cgi'
