How to use a session variable or cookies
<p>I have a main page with a large list of companies, I have a search button and if I want to find a company by state or city I can filter my search.</p>

<p>I decide to filter my search by cities,  lets say Chicago, and I get 10 companies as a result of my search.</p>

<p>I click any company in that list and I go to the company details but I realize that is not the one I am looking for, so I want to go back to my 10 companies result list but instead I go back to the main company search interface and I have to re-start my search again.</p>

<p>How to use a session variable or cookies for this case?</p>

<p>Somebody can help me with this?</p>
