That is most definitely a desirable behaviour for some users. /virtual is a separate HTTP requestm just as if the user had surfed there and crammed in the result. HTTP is stateless for various reasons. There are pros and cons to that, but it was not done on a whim.

Each "virtual" is a totally separate HTTP request, in the "stateless" HTTP protocol, and your environment variables in one will not (ever) survive to the next. 2. Apache is configured to do "virtual" requests as some kind of "sub-request" and it's all in one single HTTP request/process/thread. I *think* this is a feature I've read about in HTTP specification at http://apache.org If I'm right about all this, none of this has much to do with PHP really, and has everything to do with Apache and configuration. You'd have the same issues in mod_perl or mod_python as you are having in PHP.

By default, arrays start from 0 and work their way up, unless you supply
index names/values yourself.

You can set the lifetime of the session in php.ini. session.gc_maxlifetime is the time after which, inactive sessions will be deleted. session.gc_probability controls the percentage chance that the garbage collection (session deletion) will be triggered with each session_start(). You can also set some of the cookie parameters. All the details are in the manual, give it a try. http://www.php.net/manual/en/ref.session.php > Is there a way to open a php page in internet expl. without having a > url/adress bar > or a back and forward button , if so how do i go to work?

If they return, the session will still be active, unless it's been they wait over X minutes and the session file on the server is deleted by the garbage collection. Remember how HTTP works. All your web server does is process requests. You can't tell between requests if the user went somewhere else or not. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi,
In asp there is a session timeout function that allows the session to
end after the session is INACTIVE for x seconds/minutes ! How do i do this
in php ?
session_cache_expire(value_in_minutes);
documentation is not very clear about it, but I guess it needs to be set
before session_start()
can be set also in php.ini using session.cache_expire directive
Is there a way to open a php page in internet expl. without having a
url/adress bar
or a back and forward button , if so how do i go to work?
this is javascript
new_win = open(' url ', 'new_win_name', window_features)
you need to set right window features, check out developer.netscape.com
- client side javascript,
object window, method open
I asked this before, but say for instance - the user is busy on a secure
page , but without logging out he enters another url in the address bar.The
session
of my page , does it end or does the session carry to the next page ? If so
how can
i stop it ?
session are per domain, or if you set path using
session_set_cookie_params(), even per path. If the
user comes back within time limit, the session is still active
thanks , shaun!

In the above example, it means that ora_getcolumn() can return variables of different types. For instance, on failure, it returns FALSE (Boolean); on success, it returns a string or NULL.
