sessionid in the address
« on: May 05, 2003, 03:08:02 AM »
Just wondering, under what kind of conditions "sessionid=" shows in the address?
I noticed that on some sites it shows all the time, on my site "normaly" it shows only after u open site first time and click on any links, but next click will be without it...
but, in my logs I can see that some visitors have "sessionid=" all the time.

also, on some sites if u delete "sessionid=" from the address become logged out...

so, how does it work?

Normally, the session id is stored in a cookie. The session id is only appended to the url, if the user has disabled cookies.

I ment use "browser's session" to store current session...
so, that would help when cookies are disabled?

well, maybe there is no such a thing... but for example, if u restrict one folder at the server, by using .htaccess, that will ask visitors to login, then after u logged in, it will use some sort of session that will keep u logged in untill u close the browser. So I thought maybe its possible uses same thing at 4images?

Yes, its possible to use HTTP authentication, but it's not very comfortable (i.e. there is no real logout function possible) and not available for alle PHP installations. See: http://php.net/manual/en/features.http-auth.php

Normally, the session id is stored in a cookie. The session id is only appended to the url, if the user has disabled cookies.


Yeah, that's true but there is a slight problem (apart from the fact that the crappy IE doesn't display the SID when running without cookies ...)
I have a few static pages that are called via "index.php?template=news" for instance - they do not have a sessionID added to the URL. Is there a way that I can tell 4images to add the session ID? I tried the normally available constant SID but that doesn't work :-(

And another problem is that I have coded a few search links like "{url_search}?search_keywords=max+mustermann" - these work fine when the user has cookies enabled but with disabled cookies the parsed URL looks like this "?sessionid=804209c8f06d64fe750418662fa45346?search_keywords=max+mustermann" obviously this doesn't work; the 2nd "?" had to be replaced by "&".

Any idea how to solve these issues? I worked around the latter problem by replacing the "{url_search}" with a hard coded "./search.php". By this I lose the session ID but at least my users get proper search results. I'm now thinking about building forms with hidden fields for the search terms and to submit the form by clicking the link ...

Also one question to Jan as we are talking about sessions: why are you storing them in the database instead of PHP's default to store them in the file system? I've been told that the file system solution is quicker than database calls.

cheers,
Bernd

Technically the file system is faster because web servers are optimized for delivering files off disks.  So why not store EVERYTHING on the file system instead of the database?  A database is easier to work with, more portable, allows data relationships to be stored, etc. etc.  Quite frankly the performance difference is very small.

Yep, I agree but do you do those kind of things with the sessions? I guess not.

I'm just wondering and asked out of pure curiousity why PHP's default has been changed - no offense to anyone!
