Multiple PHP sessions within the same browser instance

Dear all.....

I am currently writing a Help-Desk / Knowledge Base application using PHP/PostGreSQL.

I authenticate the user using a quite elaborate mechanism of cookies. The problem is that using cookies (I also have a version using sessions with the same problem), I can only seem to get one user logged in from any one browser instance. (Why would I want to be logging in as two users from one browser/IP? In case I want to open another browser tab, log in as "root" or whoever, and do some administration without logging out of my other session.)

For example, say I fire up Firefox, and log into my application. A session is started for the browser. I open another tab, and login as a different user, the session (and any session variables) are "overwritten" by this new session.

I have made a workaround for the time being, by writing IP addresses and usernames to a table, and only allowing one login from any one IP address. The problem here is that if the user forgets to logout, then session_destroy() (or manual cookie cleanup, depending on the version of my application) is never called, and when I roll this out the user will be calling the DBA/SA (me!) and I'd have to DELETE FROM ip_addr WHERE username = 'blah' AND ip_addr = 'xxx.xxx.xxx.xxx' to get rid of the entry and remove the lock - something I don't want to be doing for 150 users!!!!

In short, does anyone know a way to allow multiple independant sessions with independant session IDs from the *same* browser instance?

Any help would be greatly appreciated. If not, I can still stick to my one-login-per-IP method, as all our clients use different IP addresses and the proxy is bypassed on the local network.

curlopt_cookiejar

CURLOPT_COOKIEJAR(3)					     curl_easy_setopt options					      CURLOPT_COOKIEJAR(3)

NAME

       CURLOPT_COOKIEJAR - file name to store cookies to

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIEJAR, char *filename);

DESCRIPTION

       Pass  a	filename  as  char  *,	zero  terminated.  This  will  make  libcurl write all internally known cookies to the specified file when
       curl_easy_cleanup(3) is called. If no cookies are known, no file will be created. Specify "-" as filename to instead have the cookies writ-
       ten to stdout. Using this option also enables cookies for this session, so if you for example follow a location it will make matching cook-
       ies get sent accordingly.

       Note that libcurl doesn't read any cookies from the cookie jar. If you want to read cookies from a file, use CURLOPT_COOKIEFILE(3).

       If the cookie jar file can't be created or written to (when the curl_easy_cleanup(3) is called), libcurl will  not  and	cannot	report	an
       error  for  this. Using CURLOPT_VERBOSE(3) or CURLOPT_DEBUGFUNCTION(3) will get a warning to display, but that is the only visible feedback
       you get about this possibly lethal situation.

       Since 7.43.0 cookies that were imported in the Set-Cookie format without a domain name are not exported by this option.

       The application does not have to keep the string around after setting this option.
