title: Magento - change item attribute value in quote just for this session
body: <p>I'm struggling with something and will appreciate your help.
  In Magento 1.7:
  User adding products to cart > I'm running an observer and checking some data > I want to change a product's attribute value only for that user session.</p>
  
  <p>For example: user adding a T-Shirt with attribute some_text = 'example' , now I'm checking a condition and if its true, I want to change the some_text to 'other example'. But only for that user, I don't want to save it to the product itself.</p>
  
  <p>I tried: </p>
  
  <pre><code>   foreach ($quote-&gt;getAllItems() as $item) {
          if (some_condition) {
              $item-&gt;getProduct()-&gt;setSomeText('other example')-&gt;save();
          }
      }
  </code></pre>
  
  <p>But that <strong>saves the attribute to the product and effecting all other users</strong> as well.</p>
