question regarding cookies

Hello, I am having a problem testing out the use of cookies. I'm using a tutorial from Wrox's "Beginning PHP4". It seems that I'm doing everything correctly, but when I try to access the page in my browser, I am not prompted as to whether or not I'd like to accept a cookie (which is something that I have configured my browser for), nor do the values that I assigned to the cookies show up in the test variables that I included on the page for just this purpose. In other words, I'm not sure that the setcookie() functions are working -- the variables that I set using "setcookie()" don't seem to be turning up on the page, but the standard form-based variables that I used (as values in the setcookie() function) turn up just fine. Do I need to have my web server specially configured for using cookies? I don't see anything in httpd.conf about this. My setup is as follows: Darwin 1.4.1 on PowerBook G3 (Bronze edition, no firewire) Apache 1.3.22 configured with --enable-module=most --enable-shared=max DSOs: mod_dav, mod_hfs_apple, mod_php (PHP 4.0.6)
