I've been having some problems with ActionMessages created during execution of an action which didn't display, and I found out that my problems were due to my forwards having redirect=true in struts-config.xml.

Since the default behavior is redirect=false, I've been thinking about which benefits can one have using redirect=true and I couldn't find any answer. Does anyone know when and why redirect=true should be used in action forwards?

Never show pages in response to POST

Always load pages using GET

Navigate from POST to GET using REDIRECT
