fopen does not handle redirecting URL. For example: "http://www.xanthus.net" redirects to "http://www.xanthus.net/Current". $fopen = fopen("http://www.xanthus.net", "r"); // Does not work $fopen = fopen("http://www.xanthus.net/Current", "r"); //Does work This first example redirects to the second examples URL. I was using php Version 4.0.6, but upgraded to PHP Version 4.0.8-dev hoping this would solve the problem. Here's my configure script options: './configure' '--with-mysql' '--with-gd=/usr/local/' '--with-pgsql' '--enable-inline-optimization' '--with-apxs' '--enable-versioning' '--with-gettext' Here's an

Reproduced with 4.0.6 on Win2K. It seems that fopen can only handle trailing-slash redirects on directories. Example: fopen("http://www.domain.com/some_dir", "r"); works, you're redirected to http://www.domain.com/some_dir/ but fopen("http://www.php.net/fopen", "r"); does NOT work, you're NOT redirected to http://www.php.net/manual/en/function.fopen.php
