Bug in PHP / Zend !?

Hi, i wrote yesterday that i have some Problems with $HTTP_USER_AGENT and i found out why. In the php.ini i auto-prepended some scripts (in fact one script that include some else). In one VirtualHost i added this: php_value auto_prepend_file http://host/file Which actually worked beside the fact that the Environment was pretty messed up. Anytime i add this line to the VirtualHost $HTTP_USER_AGENT reports "PHP/4.0.2" in the auto-prepended scripts (in all of them), and the right Browser-Information in the Scripts i directly call from within the virtual Host. When i remove the command from the httpd.conf the other auto-prepended Scripts report the rightBrowser-Info. First i thought that it is ok because of the fact that i include the Files over http and php is the "browser" and the whole thing is executed on another virtual host (some may call this feature), but on the other hand: I include local scripts and remote scripts and BOTH report "PHP/4.0.2" as Browser-Info. So i dunno how Zend calls these scripts, but one should report "PHP/4.0.2" and the other the Browser-Info. So i dunno how Zend handles this, but to me it looks like one Auto-Prepended File over http sets "PHP/4.0.2" as Browser-Info sets this Browser-Info for local auto-prepended Files too. Anyway, if it is ok or not, how can i use $HTTP_USER_AGENT in an included file that is executed on another server ?! regards, Guido Muehlwitz
