As we know proxies are nothing but adapterless communication. My first question is why do we need to use XI adapter.
Is it becuase it can directly interact with IE.
Second questions is , when should we use XI2.0 and XI3.0 message protocol in XI adpater. Somebody mentioned that if we use SAP Web As <6.40, we need to go for XI 2.0. But, we can't use proxies unless webas is >=6.40.
Please do correct me
