Is it by any means possible to read the browser session id using javascript?

php session_start(); $id = session_id(); echo $id; ?> This will return you the current session id.
Session IDs are typically found in the Request (NCSA) field, the URI-Query (W3C), or the Cookie field: If the ID is found in the URL itself, it will be in the Request field for Apache servers and in the URI Query field for IIS servers.
A session ID is a unique number that a Web site's server assigns a specific user for the duration of that user's visit (session). The session ID can be stored as a cookie, form field, or URL (Uniform Resource Locator). Some Web servers generate session IDs by simply incrementing static numbers.
A session-id is obtained by taking an MD5 hash over 128- bits generated using one of Java's pseudo-random number generators (PRNG).
Yes. As the session ID is either transported over the URL (document.location.href) or via a cookie (document.cookie), you could check both for the presence of a session ID.
