Jonathan, Thanks a lot for your comments . Actually, the problem I currently face is how to provide maximum reliability (if this word is applies) in terms of http load balancing. Well, I definitely understand your constraints regarding professional consultancy and thank you again for your valuable comments. I will investigate more on the issue and hope to find a proper solution; being a technical approach or just as you suggested, a statement of non-applicability. Thanks in advance.
