Internet Explorer ragiert auf keine Session Variablen

[Raucherkrebs]

Ich habe ein total merkwürdiges Problem.
Mein Internet explorer erkennt keine Sessions. Ich bin auf Windows 2000. Meine Seite funzt im Firefox einwandfrei. Das ist vielleicht komisch. Woran kann das liegen? Hier ein Auszug meiner php.ini:

[Session]
; Handler used to store/retrieve data.
session.save_handler = files

; Argument passed to save_handler.  In the case of files, this is the path
; where data files are stored. Note: Windows users have to change this
; variable in order to use PHP's session functions.
;
; As of PHP 4.0.1, you can define the path as:
;
;     session.save_path = "N;/path"
;
; where N is an integer.  Instead of storing all the session files in
; /path, what this will do is use subdirectories N-levels deep, and
; store the session data in those directories.  This is useful if you
; or your OS have problems with lots of files in one directory, and is
; a more efficient layout for servers that handle lots of sessions.
;
; NOTE 1: PHP will not create this directory structure automatically.
;         You can use the script in the ext/session dir for that purpose.
; NOTE 2: See the section on garbage collection below if you choose to
;         use subdirectories for session storage
;
; The file storage module creates files using mode 600 by default.
; You can change that by using
;
;     session.save_path = "N;MODE;/path"
;
; where MODE is the octal representation of the mode. Note that this
; does not overwrite the process's umask.
session.save_path = "/tmp"

; Whether to use cookies.
session.use_cookies = 1

; This option enables administrators to make their users invulnerable to
; attacks which involve passing session ids in URLs; defaults to 0.
; session.use_only_cookies = 1

; Name of the session (used as cookie name).
session.name = PHPSESSID

; Initialize session on request startup.
session.auto_start = 0

; Lifetime in seconds of cookie or, if 0, until browser is restarted.
session.cookie_lifetime = 0

; The path for which the cookie is valid.
session.cookie_path = /

; The domain for which the cookie is valid.
session.cookie_domain =

; Handler used to serialize data.  php is the standard serializer of PHP.
session.serialize_handler = php

; Define the probability that the 'garbage collection' process is started
; on every session initialization.
; The probability is calculated by using gc_probability/gc_divisor,
; e.g. 1/100 means there is a 1% chance that the GC process starts
; on each request.

session.gc_probability = 1
session.gc_divisor     = 1000

; After this number of seconds, stored data will be seen as 'garbage' and
; cleaned up by the garbage collection process.
session.gc_maxlifetime = 1440

; NOTE: If you are using the subdirectory option for storing session files
;       (see session.save_path above), then garbage collection does *not*
;       happen automatically.  You will need to do your own garbage
;       collection through a shell script, cron entry, or some other method.
;       For example, the following script would is the equivalent of
;       setting session.gc_maxlifetime to 1440 (1440 seconds = 24 minutes):
;          cd /path/to/sessions; find -cmin +24 | xargs rm

; PHP 4.2 and less have an undocumented feature/bug that allows you to
; to initialize a session variable in the global scope, albeit register_globals
; is disabled.  PHP 4.3 and later will warn you, if this feature is used.
; You can disable the feature and the warning separately. At this time,
; the warning is only displayed, if bug_compat_42 is enabled.

session.bug_compat_42 = 0
session.bug_compat_warn = 1

; Check HTTP Referer to invalidate externally stored URLs containing ids.
; HTTP_REFERER has to contain this substring for the session to be
; considered as valid.
session.referer_check =

; How many bytes to read from the file.
session.entropy_length = 0

; Specified here to create the session id.
session.entropy_file =

;session.entropy_length = 16

;session.entropy_file = /dev/urandom

; Set to {nocache,private,public,} to determine HTTP caching aspects
; or leave this empty to avoid sending anti-caching headers.
session.cache_limiter = nocache

; Document expires after n minutes.
session.cache_expire = 180

; trans sid support is disabled by default.
; Use of trans sid may risk your users security.
; Use this option with caution.
; - User may send URL contains active session ID
;   to other person via. email/irc/etc.
; - URL that contains active session ID may be stored
;   in publically accessible computer.
; - User may access your site with the same session ID
;   always using URL stored in browser's history or bookmarks.
session.use_trans_sid = 0

; Select a hash function
; 0: MD5   (128 bits)
; 1: SHA-1 (160 bits)
session.hash_function = 0

; Define how many bits are stored in each character when converting
; the binary hash data to something readable.
;
; 4 bits: 0-9, a-f
; 5 bits: 0-9, a-v
; 6 bits: 0-9, a-z, A-Z, "-", ","
session.hash_bits_per_character = 5

; The URL rewriter will look for URLs in a defined set of HTML tags.
; form/fieldset are special; if you include them here, the rewriter will
; add a hidden <input> field with the info which is otherwise appended
; to URLs.  If you want XHTML conformity, remove the form entry.
; Note that all valid entries require a "=", even if no value follows.
url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=fakeentry"

Habe das Problem gefunden: http://de.php.net/session

There's a bug in Internet explorer in which sessions do not work if the name of the server is not a valid name. For example...if your server is called web_server (_ isn't a valid character), if you call a page which uses sessions like http://web_server/example.php your sessions won't work but sessions will work if you call the script like this

[IP NUMBER]/example.php

Took me a lot of time to find out why my PHP sessions worked perfectly in Firefox and Opera but they didn't work in internet explorer.

ALSO KEINE UNTERSTRICHE IN SERVERNAMEN BENUTZEN!

Ich würde ja vielmehr vermuten, dass die Cookies mit Servernamen, die keine Punkte enthalten, ein Problem machen. Bekanntlich gibt es Filtermaßnahmen, die verhindern, dass ein Cookie, welches für ".com" oder andere Top-Level-Domains dieser Länge gesetzt wird, vom Browser akzeptiert wird. Ansonsten würde es an alle Server mit ".com" im Namen gesendet werden. Deshalb gibt es die Vorschrift, dass die Domains für Cookies mindestens ZWEI Punkte enthalten müssen.

Ein Servername der Form "web_server" enthält keine Punkte - und deshalb funktionieren die Cookies wohl auch nicht. Ob der Unterstrich relevant ist, mag ich nicht zu sagen. Richtig ist in jedem Fall, dass dieses Zeichen in Domainnamen nicht erlaubt ist.

Hi,

Du meinst also, Server mit Namen wie "localhost" machen Probleme mit Cookies?
Kann ich nicht nachvollziehen. In keinem meiner Cookie-fähigen Browser.

Mein Internet explorer erkennt keine Sessions.

Wie aeussert sich das?
