Hi kheeteck,
as said before - a session id at the end of the URL (as path info, GET parameter
or POST parameter) will not stay there if you don't modify all displayed html
pages. As I understand, you can't modify these pages because thay are on another
server. That means you also can't use a leading session id. Bad. There is only
one way left to store information on the browser's side: Cookies.

Nachrichtentext:
Hi Michael :
I am really glad that you reply to my mail.. as i have been trying to solve
this problem for quite some time....
Hmm , however i think u slightly misunderstand what i mean..
What i mean is...
For eg,
I have a html page which contains a form page let say allowing the user to
enter certain values... like colorNo etc.
This values would be posted to my server and the data would be stored in a
database(mysql) together with a unqiue
session id which would be generated. ( for this part i have finished and is
working).
Now comes the problematic part, after the values are submitted. I want this
value to be avaiable to me each time
as user enter a new url from the browser( take note this url is not the
content residing in my server.. it is any remote site url).
The only way is to append a session id at the url.
So for instance.. after the user finished entering the form page. He can now
access any urls(remote site). How do i tell the server that this is the user
who has entered the form earlier based on the session id generated. And for
all the subsquent links... how can i append the session id.
I would greatly appreciated if you could help me out..
Really thanks to you
Regards
kheeteck
