Hi!
I've got an unusual problem here. I'm trying to write a PHP script that
behaves like a web client. Why? I want to automatically check specific
URLs for changes.
I'm using file_get_conten ts(URL) to read the pages and this seems to
work just fine as long as there are no logins, sessions or cookies.
But I'm getting a new PHPSESSID from the site whenever I get a new page
(or refresh the same page) even though I did a login through the URL
(...login.php?u ser=...&pass=.. .) and it seemed to work. So the login
does not really work.
So what do I have to do to make the login stick? Use a different way to
read the pages? Work with sessions? Cookies?
Don't forget that the script is not running on a server, it is the
client! I have not found any documentation for this rare case.
I'm curious if any of the PHP pros out there knows an answer to this
problem. If anyone does, an answer would be appreciated. Thanks in
advance.

You should use a different way to request URLs. How are you requesting
them now? fopen? There are many intelligent ways to implement scripts
that pretend to be http clients. curl might be available on your
machine. Else there are classes like snoopy or the httpclient class in
PEAR. These will make handling cookies easier...

Hi,
Are you passing the PHPSESSID back to the server in your URLs?

I did this a couple times using fsockopen (though I hear CURL is good),
extracted the cookie information, and resent the cookie info with each request.
Read the manual and especially the comments for fsockopen. You may find you
need to send some other, custom headers (notably user agent) for some sites, as
the default settings may be interpreted as spambots.

No. I have already thought of that trick but it doesn't work.

Could you please elaborate on that?

Could you give me some lines of sample code how to request and store a
page in a string variable with fsockopen? Which custom headers do you
think are required and how do I send them?

Hi Gurus
I am basically sorry that I have to bother you about this. I am a PHP
beginner and I have been studying sessions and cookies over the last few
weeks. I have learned lots, but I am missing the big picture.
Is it like this:
1. user comes to site
2. user does something (e.g. a search) that may be useful later => session

Now we want people to be able to read some pages from outside so I

Does Python have sessions like PHP?
If not should I roll my own from a cookie and a MySQL table?

I really need to use cookieless ASP sessions with ASP 3 (IIS5)
Can I find out the session ID from the first page, then post it or send it
with the url to the next page, then at the start of the next page asp, set
the session ID from the value retrieved from the URL?
How do you manually set the session ID?

According to the docs you tell ASP.NET to use cookieless sessions by setting
a value in the config.web file.
However, what if I wanted to determine at run time whether or not I wanted
to use cookieless sessions for a particular user, and if so, I'd instruct
ASP.NET to turn on cookieless sessions for a particular user session. Is
this possible?
For example I want to use cookie based sessions by default for all users.
But if a user has...

Hi
I'm using several Sessions in my app. When the user has cookies enabled in
their browser, everything works fine. But with cookies disabled, only IE
seems to remember the sessions. In Firefox and Safari, the session values
seem to be "forgotten".
I've looked around on Google but can't find any solutions to this problem.
Plus I don't know how debug with Firefox (eg. step through the code).

I'm developing a site where I'd like to store information during a users

not possible to control for how long a session is valid. It seems that
these information are valid until the browser closes.
On the other hand it's possible to set expiration time for cookies.
Does this mean that I have to abanbon $_SESSION altogether and switch to

Suppose I have an HTML form that sends data to a PHP script, "post"
method.
If this script generates a page with a link to another script, will the
latter script get the former's $_POST data when the user clicks on the
link?
If not, is there a straightforward way (i.e.: no saving to files or
cookies) to "post" the data to the latter script without using a form?

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
