I have an idea about developing web application using Ruby on Rails.
But I don't know how to develop a web application using only ruby
without rails. Is it possible? If possible how can I handle requests,
actions, responses etc., Please clear my doubt as early as possible.
Thanks

Hi,
I am currently developing Ruby (not rails) web applications for mobile
phones - so yes, you don't need rails.
To get some basic information about the cgi version, i recommend
starting here:
http://www.ruby-doc.org/docs/ProgrammingRuby/html/web.html
You can get information about eruby and mod_ruby (for apache) from this
site:
http://modruby.org/en/
These are not frameworks, they just execute ruby code. If you are using
apache, it is fairly straightforward to set up the eruby executable to
handle your requests for you and you just basically embed ruby inside
html like this:
<div>This is HTML</div>
<% print "this is ruby" %>
etc.
A tutorial can be found here:
http://www.hiveminds.co.uk/node/3094
With mod_ruby or fastcgi, you can get even more control over the
response, you can create a small ruby program that catches the request
and generates the whole response.
print "HTTP/1.1 200 OK\n"
print "Content-Type: text/plain\n\n"
print 'Static text.'
is a very simple handler that just displays that static text. Of course,
as Robert mentioned before, you can use CGI to help you, like:
require 'cgi'
c = CGI.new
print c.header('type'=>'text/plain')
print 'Static text.'
Hope this helps.
