[SOLVED] the best practice for performance bettween using parameter in url ?p=2 and Managed bean

the best practice for performance bettween using parameter in url ?p=2 and Managed bean

I am using JSF 2.0 and Icefaces and Glassfish for my project and I want to optimise this application the best I can, and I want to know what is the most optimized method to send parameter.

first 1: using /BackOffice/test.xhtml?id=7 in url and String a=(String) FacesContext.getCurrentInstance().getExternalContext().getRequestMap().get("id"); in the bean with @RequestScoped and

<f:metadata>
        <f:viewParam name="id"  value="#{id}">
        </f:viewParam>
    </f:metadata>

in the jsf

or the second : using backing bean with @SessionScoped

Solution

If you want to optimize you should start with profiling, I highly doubt the difference between these two will be of any significance.

Request parameters should be passed as request parameters as you will otherwise break bookmarks, browser history, search engine indexing and caching.
