Multi VF Page Redirects Using Single Controller

Hi Awesome Developers,

Have you ever thought of redirecting to multiple pages using a single controller, here is what I have come up with the scenarios of redirecting to different pages using same controller.

Scenario 1:
Main Page
<apex:page standardController="Account" extensions="PageRedirectDemo">
    <apex:form>
         <apex:inputtext value="{!strReceivedText}" /> <br/>
         <apex:inputtext value="{!objAccount.Id}" />
         <apex:commandbutton action="{!redirect}" value="Redirect"/>
   </apex:form>
</apex:page>

Controller :
public with sharing class PageRedirectDemo
{
   public string strReceivedText{get;set;}
   public Account objAccount{get;set;}

   public PageRedirectDemo(ApexPages.StandardController stdController){
         objAccount = (Account)stdController.getRecord();
   }

   public pagereference redirect(){
      PageReference ref = new PageReference('/apex/RedirectedPage'+'?id='+objAccount.Id);
      ref.setRedirect(false);
      return ref;
   }

}

Redirected Page
<apex:page standardController="Account" extensions="PageRedirectDemo">
 <apex:outputLabel>Value received from Page 1</apex:outputLabel> <br/>
 <apex:outputText> {!strReceivedText } </apex:outputText>
</apex:page>

Output :











The above will work well if I keep the signature of second page same as first. Now I have changed the signature of the second page as below and added empty constructor in the controller.

<apex:page controller="PageRedirectDemo">
 <apex:outputLabel>Value received from Page 1</apex:outputLabel><br/>
 <apex:outputText> {!strReceivedText } </apex:outputText> <br/>
  <apex:outputtext value="{!objAccount.Id}" />
</apex:page>

public with sharing class PageRedirectDemo
{
   public string strReceivedText{get;set;}
   public Account objAccount{get;set;}

   public PageRedirectDemo(){
   }
   public PageRedirectDemo(ApexPages.StandardController stdController){
         objAccount = (Account)stdController.getRecord();
   }

   public pagereference redirect(){
      PageReference ref = new PageReference('/apex/RedirectedPage'+'?id='+objAccount.Id);
      ref.setRedirect(false);
      return ref;
   }

}

You can see the values are not set due to change in signature,

Scenario 3 :
MainPage :
<apex:page controller="PageRedirectDemo">
    <apex:form>
         <apex:inputtext value="{!strReceivedText}" /> <br/>
         <apex:commandbutton action="{!redirect}" value="Redirect"/>
</apex:form>
</apex:page>

public with sharing class PageRedirectDemo
{
   public string strReceivedText{get;set;}
   public PageRedirectDemo(){
   }

   public pagereference redirect(){
      PageReference ref = new PageReference('/apex/RedirectedPage');
      ref.setRedirect(false);
      return ref;
   }

}

RedirectedPage
<apex:page controller="PageRedirectDemo">
 <apex:outputLabel>Value received from Page 1</apex:outputLabel><br/>
 <apex:outputText> {!strReceivedText } </apex:outputText> <br/>
</apex:page>

Output :

*IMP : Observe the URL in each scenario :)

Happy Redirecting ;)
