Rails core - Mar 2006 - relative_url_root?

Hey All,

Could someone explain why relative_url_root is hardcoded to only work
with apache:

request.rb (154:158):
   # Returns the path minus the web server relative installation directory.
   # This method returns nil unless the web server is apache.
   def relative_url_root
     @@relative_url_root ||= server_software == ''apache'' ?
@env["SCRIPT_NAME"].to_s.sub(/\/dispatch\.(fcgi|rb|cgi)$/,
'''') : ''''
   end

I''d like to use it with lighttpd as well.  I''ll submit a patch
but
just wanted to check the thinking on why it was restricted to apache
in the first place.

Also, how would you feel about a patch to let you specify the relative
url as an env variable (i.e. RAILS_RELATIVE_URL_ROOT)?  Seems like a
good candidate for something to be set by the server config file.

Thanks!

Because lighttpd doesn''t set SCRIPT_NAME in the way we require.

If you figure out a way to implement the auto-detection, create a  
ticket and assign me as owner.

For the time being, it''s not especially tricky to set the root in  
environment. (Although we should add a configuration option for it...)
