    Why don't you want to use query parameters? – Phil W Sep 10 at 10:47
  • You can use Platform Cache or store in an Object for this if you really want not to pass anything in the param. – Arabinda Sep 10 at 10:57

You can use Apex Cookies to pass values between pages. Here's a working demo.

On PageOne, whatever value user enters in the input box, that value will be stored in greeting cookie and will be retrieved on PageTwo and displayed on the page.

// Page One

<apex:page controller="PageOneCtrl" docType="html-5.0">
    <apex:form>
        <apex:pageBlock>
            <apex:pageBlockSection collapsible="false" columns="1">
                <apex:pageBlockSectionItem>
                    <apex:outputLabel>Greeting: </apex:outputLabel>
                    <apex:input type="text" value="{!greeting}" />
                </apex:pageBlockSectionItem>
            </apex:pageBlockSection>
            <apex:pageBlockButtons>
                <apex:commandButton value="Set Cookie" action="{!setCookieAndNavigate}" />
            </apex:pageBlockButtons>
        </apex:pageBlock>
    </apex:form>
</apex:page> 

// Page One Controller

public class PageOneCtrl {

    public String greeting {get; set;}

    public PageReference setCookieAndNavigate(){
        Cookie c = new Cookie('greeting', greeting, null, -1, false);
        ApexPages.currentPage().setCookies(new Cookie[]{c});
        PageReference pageRef = Page.PageTwo;
        return pageRef;
    }
}

// Page Two

<apex:page controller="PageTwoCtrl">
    Hello, {!greeting}.
</apex:page>

// Page Two Controller

public class PageTwoCtrl {

    public String getGreeting(){
        Cookie greeting = ApexPages.currentPage().getCookies().get('greeting');
        return greeting.getValue();
    }
}

Hope this helps.

  • Both VF page has same controller. In this case how to read the value and populate the data in input field(on Load). – user3214361 Sep 11 at 17:27
  • @user3214361 In your original post you have mentioned that your pages use different controllers. Anyways you can try and update your code and @ message me to look into it. – jagmohan Sep 12 at 14:04
