Hii all,

This is how running smruti_exp as service
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\smruti_exp\Parameters]
Application=ruby
AppParameters=script\server -b 192.168.247.49 -p 3000
AppDirectory=D:\work\Smruti1\src

am running mongrel to do all work,but i would like to run apache server
as front server ,so i made some chnges in http.conf files come with
Apache

#Rewrite stuff
RewriteEngine On

Check for maintenance file and redirect all requests

RewriteCond %{DOCUMENT_ROOT}/system/maintenance.html -f
RewriteCond %{SCRIPT_FILENAME} !maintenance.html
RewriteRule ^.*$ /system/maintenance.html [L]

Rewrite index to check for static

RewriteRule ^/$ /index.html [QSA]

Rewrite to check for Rails cached page

RewriteRule ^([^.]+)$ $1.html [QSA]

Redirect all non-static requests to cluster

RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
RewriteRule ^/(.*)$ balancer://src_cluster%{REQUEST_URI} [P,QSA,L]

these are the changes i made and in host file
i added
192.168.247.49 src
