Which works as a better reverse proxy: Apache or Webdispatcher?
Could any guru compare them? Thanks!

To my knowledge, the Webdispatcher works more better
The Pros and cons of a Apache reverse proxy
Re-use existing infrastructure
Unified Web infrastructure for all Web systems (SAP and non-SAP)
Less integrated with SAP Web AS
Configuration, operation, maintenance requires special expertise
SAP Web Dispatcher
The SAP Web dispatcher is located between the Web client (browser) and your SAP system that is running the Web application.
It forwards the incoming requests (HTTP, HTTPS) in turn to the application server (AS) of the SAP system. The number of requests that are sent to an AS depends on its capacity. The capacity of an AS ABAP depends on the number of configured dialog work processes. The capacity of a AS Java depends on the number of Server Processes. If the application is stateful, the SAP Web dispatcher ensures that with the next request, the user is forwarded to the server that is processing his or her application. To do this, it uses the session cookie with HTTP connections, and the client IP address with end-to-end SSL.
