How to disable ONGL expression evaluation for the information followed by "redirect"?

I'm using Apche struts2 version 2.3.14.2 to develop web app.

I came across a method in (setEnableEvalExpression) OnglUtilit.java to disable the ONGL expression evaluation.

Can I disable ONGL expression evaluation on the information following "redirect"?

Or Is there any other way to disable ONGL expression evaluation?

Thanks!
