You can store and read string information in a cookie   If it is a session id coming from the server  the server can generate this cookie  And when another request is sent to the server the cookie will come too  Without having to do anything in the browser   However if it is javascript that creates the session Id  You can create a cookie with javascript  with a function like   The read function work from any page or tab of the same domain that has written it  either if the cookie was created from the page in javascript or from the server

I think you misunderstood the concept of session  session is a server side per-user-data-store which allows you to save user data on the server side   thus  you have 2 options  resort to use cookies  which will give the illusion of session but not quite the same   you can access cookies very simply by document cookie    but  if you want your server be aware of the session  you need to use some sort of server request probably the best way is to use AJAX to do this   I would recommend you to re-read the definition of sessions

You can use the name attr      lt script type  text javascript   gt    window name   This is my session      lt  script gt     You still have to develop for yourself the format to use  or use a wrapper from an already existing library  mootools  Dojo etc   You can also use cookies  but they are more heavy on performance  as they go back and forth from the client to the server  and are specific to one domain

You can use sessionStorage it is similar to localStorage but sessionStorage gets clear when the page session ends while localStorage has no expiration set   See https   developer mozilla org en-US docs Web API Window sessionStorage

If you create a cookie and do not specify an expiration date  it will create a session cookie which will expire at the end of the session   See https   stackoverflow com a 532660 1901857 for more information

You can store and read string information in a cookie   If it is a session id coming from the server  the server can generate this cookie  And when another request is sent to the server the cookie will come too  Without having to do anything in the browser   However if it is javascript that creates the session Id  You can create a cookie with javascript  with a function like   function writeCookie name value days        var date  expires      if  days            date   new Date            date setTime date getTime    days 24 60 60 1000            expires      expires     date toGMTString                 else          expires                 document cookie   name         value   expires      path         Then in each page you need this session Id you can read the cookie  with a function like   function readCookie name        var i  c  ca  nameEQ   name            ca   document cookie split           for i 0 i  lt  ca length i              c   ca i           while  c charAt 0                      c   c substring 1 c length                     if  c indexOf nameEQ     0                return c substring nameEQ length c length                       return         The read function work from any page or tab of the same domain that has written it  either if the cookie was created from the page in javascript or from the server   To store the id   var sId    s234543245   writeCookie  sessionId   sId  3     To read the id   var sId   readCookie  sessionId
