Hello Harsh,
I'd consider using the Cache with SQL based dependencies (SQL server should be a part of farm)
google to find samples or see MSDN

HT> I have some confusion over refreshing the cache in web farming
HT> environment.
HT> HT> We have two sites: 1) Admin site 2) Client Site
HT> HT> We are maintaining many things in cache. Out of which one is say for
HT> example for 'Top-5 Item' Control we are maintaining.
HT> HT> When admin site updates the price of any item from Top-5 Item
HT> Control, it should be reflected immedietly in Client Site.
HT> HT> Now, my Admin site address is, http://sitenameadmin.com/ and my
HT> Client site name is http://Sitename.com. Both are configured
HT> separatly in the IIS, as two web sites.
HT> HT> Earlier, what I have done is...I have made one web service page at
HT> client site. So when admin updates anything from Top-5 item control,
HT> it will call the web service of Client site, and pass the CacheID,
HT> as input parameter. Client site web service is delete that cache,
HT> and will refill it.
HT> HT> It all works OK till this.
HT> HT> Now the problem scenario arise...Client has now asked us to deploy
HT> the
HT> client site (only client site) in web farming environment.
HT> He will create four server, on which we need to deploy our
HT> application. In the above scenario, I feared that the solution will
HT> not
HT> going to work. Because, if admin site calls web method it is not
HT> confirmed that cache from all web server will be refreshed.
HT> The URL of the site will be http://Sitename.com, and network load
HT> balancer will transfer the request to any one of server behind the
HT> farm.
HT> HT> This is the detail senario, of my problem.
HT> HT> I am confuse on how to call diffrent servers in a farm one by one,
HT> or how to add the address in the web.config file.
HT>
