OS: Redhat Linux 2.4.18
Apache Version: 1.3.27
Configure Command =>  './configure' '--prefix=/usr/local' '--with-apache=../../apache_1.3.27' '--enable-exif' '--enable-track-vars' '--with-calendar=shared' '--enable-magic-quotes' '--enable-trans-sid' '--enable-wddx' '--enable-ftp' '--enable-inline-optimization' '--enable-memory-limit' '--with-gd=/usr/local' '--with-zlib' '--enable-gd-native-tt' '--with-t1lib=/usr/local' '--with-jpeg-dir=/usr' '--with-png-dir=/usr' '--with-zlib-dir=/usr' '--with-ttf' '--with-freetype-dir=/usr/local' '--with-mhash=/usr/local' '--with-mcrypt=/usr/local' '--with-pdflib=/usr/local' '--with-tiff-dir=/usr' '--with-jpeg-dir=/usr' '--with-zlib-dir=/usr' '--with-openssl=/usr' '--with-curl=/usr' '--with-ldap'



Reproduce code:
---------------
#!/usr/bin/php
<?php
setcookie("name","value",0,"/",".mydomain.com");
echo "Content-type: text/html";
echo "You should now have a cookie.";
?>

Expected result:
----------------
I expect that the cookie warning feature of my web browser would alert me to an incoming cookie.

Actual result:
--------------
No cookie alert is triggered nor is one written when setting a 'persitent' cookie.
