I am trying to use Coherence*Web for HTTP Session Management and the details are as under:
Environment: Coherence Grid is runing in a different subnet than the App Servers
Please help me with the following questions:
1. What would be the ideal architecture for HTTP Session Management in the given environment?
2. What would be the performance implication of using Coherence*Extend over the Distributed Caching? Any performance test results available?Since there are extra network hops involved, the performance impact is non-zero. Plenty of customers have used an Extend configuration, the impact on your application will depend on your network performance and application session size. We have not published any performance numbers.
3. What could be the issues if Extend is used for HTTP Session Management?Extend is supported with Coherence*Web, please see the product documentation for the special configuration recommendations.
Thank you and look forward to hearing from you.
