title: Apex : your session has expired
body: <p>I have an apex application.</p>
  
  <p>When the user subscribes,he receives a mail to validate his account. In the mail there is a link he has to click on. Once the user clicks on the links he is redirected to a page in my application that validates his account.</p>
  
  <p>This scheme works perfectly.</p>
  
  <p>However when the user tries to submit new things (basically logs in) I get the error message : Your session has expired.</p>
  
  <p>It seems like, when he subscribes, my app creates a session. And when he clicks the link on the email, the app creates a new session id. </p>
  
  <p>Is there any way to clear all the caches when loading the login page please ?</p>
  
  <p>I tried the solution here but it's not working : <a href="https://docs.oracle.com/database/121/HTMDB/concept_ses_val.htm#BEIHCICF" rel="nofollow noreferrer">https://docs.oracle.com/database/121/HTMDB/concept_ses_val.htm#BEIHCICF</a></p>
  
  <p>I still get the same error : Your session has expired.</p>
  
  <p>Any ideas please ?</p>
  
  <p>Thanks.</p>
