title: How to read/parse correctly GA Custom Variable?
body: <p>I'm sorry for possible duplicate (I did not find answer)</p>
  
  <p>I need to read value from cookie page, that is actually 'google analytics Custom Variable'. We set it like that</p>
  
  <pre><code>tracker._setCustomVar(1, 'myvar', 'myvalue', 1);
  </code></pre>
  
  <p>as result I have variable __utmv with some value in cookie, i.e.</p>
  
  <pre><code>12345678.|1=myvar=myvalue=1
  </code></pre>
  
  <p>I'm wondering if I simply can take everything after 'myvar=' and before '=1'? Maybe there is an 'official' way how it should be done?
  I'm not sure if that format will be always same/similar and if I can expect that value ends with '=1'? and if so, what if my value has substring '=1', should I care about that?</p>
  
  <p>thanks</p>
