I am trying to create the session once page load but it’s not creating. Because all page are open through link for example I have two page index.inc and test.inc so in index page I define 3 or more link and all like open the same page test.inc, even I create different register session variable each clicking but once I click the first link it will open the page and set the session variable value but next time once I click the second link then it can't change the previous session value even if multiple user work on same page then for this instance I can't delete the session so only one option is there to over write the session value. So please help me it is really very urgent.
So how to create the session in drupal. Give me idea with syntax.
