[PHP] Re: Passing variables between servers
You cannot avoid using cookies. When you use Sessions web server is making use of cookies (unless you go for URL rewriting) which remains in the browser until one quits the browser. To tackle your situation, you can effectively make use of a database table and a session cookie: 1. set a session cookie (different from one set by the server) as a soon as as a login is successful. This cookie should be set in such a way that the browser will send it back to any server in your domain. The value for this cookie can be the same as the value PHP generated for the Session ID. If you prefer to use some other value make sure that it is different for each session for each user to avoid security issues. 2. Store this value and the user ID (or something else to identify that user in your app) in a table. 3. Remove this row from the table when the user logs out or on Session timeout. Now, when the user is taken to your ASP server, browser will send that cookie set by the PHP server along with the request and the ASP server can query the database for that cookie value to get the user ID. If it can find it in the table the application can make sure that the request is valid and the rest of the info can be pulled from the database.

[PHP] Re: Passing variables between servers
Is there any reason to pass the data to the ASP server other than the need for the ASP server to pass it back in case the PHP server session has expired? If not, why not just store the login information in a local table referencable by a primary key that you pass around instead? You could even do this with GET. --- Seairth Jacobs [EMAIL PROTECTED] Mark McCulligh [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I have two server.

The session variables are need on both server for authorization needs. The two servers host two separate Intranet apps and I am trying to join the two together into one Intranet app. The variable will be used on both sides. The reason I don't what to use cookie is your users keep disabling them. They think a web site can use a cookie to break into their computer. They also disable JavaScript a lot too. _ Mark McCulligh, Application Developer / Analyst Sykes Canada Corporation www.SykesCanada.com [EMAIL PROTECTED] - Original Message - From: Seairth Jacobs [EMAIL PROTECTED] Newsgroups: php.general To: [EMAIL PROTECTED] Sent: Wednesday, August 21, 2002 2:18 PM Subject: Re: Passing variables between servers Is there any reason to pass the data to the ASP server other than the need for the ASP server to pass it back in case the PHP server session has expired?

Re: [PHP] Re: Passing variables between servers
I have thought about this also, but I need the variables in the ASP session and I don't have the time line to rewrite the ASP pages over in PHP. The current ASP app took a year to develop. I have thought about having PHP on both servers and having the PHP on the 2000 server just save the variables to a XML file or ini file, then have the ASP code read it in, but I thought there is probable some easy solution out there for passing information around. cURL looked like a solution but I can't find information on it using ASP. Maybe I am looking of a easy solutions that doesn't exist and will have to just use the longer one.

[PHP] Re: Passing variables between servers
Why not share a session DB across both servers?
Since your users disable cookies you'll have a url that looks
like this anyway: http://www.myPHPserver.com/index.php?sid=12345
if you wanted to maintain session state
so, when redirecting to the ASP server do:
header('location: http://www.myASPserver.com/default.asp?sid=12345')
then have default.asp open the DB that has the sessions for
the PHP server through ODBC or ADO or whatever and match the
session id pulling out the stored info for that session.
