<p>I have a general question about sessions. I am not very seasoned when it comes to this subject. I've tried with: </p>
<pre><code>NewRediStore (gopkg.in/boj/redistore.v1)
NewCookieStore
NewFileSystemStore
</code></pre>
<p>I was under the impression that sessions could last between server restarts, hence the need for a 'store'. While my golang backend is running, I am able to set new sessions and retrieve them for multiple users/browsers. No problems there. When I restart my server, I notice that all session access results in <code>session.IsNew == true</code>. </p>
<p>In Redis, I can see all the session keys after the restart, and even verified that <code>.Get</code>ting the session results in the right ID retrieved, but <code>IsNew</code> is still set. </p>
<p>I guess intuitively, this makes sense because there must be some map in memory that leads to the setting of <code>IsNew</code> but I would think that if there was any hit to the store, IsNew should not be set. Am I going crazy? Is there something easy that I am doing wrong? Is this a fundamental misunderstanding of how to use sessions?</p>
<p>Please let me know if I need to include code or additional details.</p>

<p>Use <code>gob</code> when you put the data in <strong>and</strong> when you try to take it out.</p></pre>gohacker: <pre><p><code>func NewCookieStore(keyPairs ...[]byte) *CookieStore</code></p>
<p><code>keyPairs ...[]byte</code></p>
<p>changing key pairs = invalidating the sessions</p></pre>
