Load balancing solutions will let you run on multiple servers but both respond to a single domain/ip address endpoint. Software like Network Load Balancing built into Windows Server or hardware solutions will allow you to do this.
Basically you just built your app or apps to run all on one machine and then you replicate the site(s) out to another machine (presumably using a central data store). The load balancer will then re-direct inbound traffic to one of the two machines based on load and various other rules.
You should look at this very carefully though - introducing load balancing introduces a whole new level of complexity into application management. It's much easier (if possible) to instead invest that money into higher end hardware and try to keep everything running on a single box with possibly a replicated setup for backup rather than running load balancing.

I have developed a website and publish successfully using a domain name like www.xxx.org. Later, a need arise to link a web application developed on other server so that it could be accessible via internet though the web site. I have seen about web fram , but I am not clear about how to access 2 web rsources on 2 servers (on same domain)using a single Url. Can any assist me or share me his/her experience on the subject? Thanks
