I have an asp.net mvc5 web application which has 5 pages. The information on the last three pages are passed from the first two. So it’s like my first two pages are dynamic and last three changes according to the first two.  

My program is only doing the following thing  

I fill information in first page, hit submit button via post request, fill information in second page and hit submit button from second page. The rest pages display the result only.  

**But the problem arises when I press back button from browser form second page, change some value in first page and press submit button, I lose all the data from the second page. I want the second page retain its state whatever it was before.**  

I really don’t know how hard it is. So can some please advise me how to resolve that problem?
Thanks in advance.Here is just Sample code to illustrate This is the second page 

```html
<form action="thirdpage.cshtml" method="post">
          MARKET VALUE OF HOUSE 2nd page:
         <input id="MVOH" type="number" step="any" name="MVH" /><br/><br/>

           MORTGAGE OWING 2nd page:
           <input id="MO" type="number" step="any" name="MOwing" /><br/><br/>
            MORTGAGE REPAYMENT 2nd page
            <input id="MPPM" type="number" name="MP" />
            <select id="Sel">
                 <option value="0">Per week</option>
                  <option value="1">Per fortnight</option>
                   <option value="2">Per Month</option>
              </select><br/><br/>
            <div>  

              <input id="next" type="submit" value="Income Expenses &raquo;"/>   
          </div>  
   </form>
```

And the first page is

```html
 <form action="secondpage.cshtml" method="post">

                   MARKET VALUE OF HOUSE:
                    <input id="MVOH" type="number" step="any" name="MVH" /><br/><br/>

                    MORTGAGE OWING:
                    <input id="MO" type="number" step="any" name="MOwing" /><br/><br/>
                    <td>MORTGAGE REPAYMENT</td>
                    <td>
                        <input id="MPPM" type="number" name="MP" />
                        <select id="Sel">
                            <option value="0">Per week</option>
                            <option value="1">Per fortnight</option>
                            <option value="2">Per Month</option>
                        </select><br/><br/>
            <div>  

                <input id="next" type="submit" value="Income Expenses &raquo;"/>

            </div>

        </form>
```
