#19265 [Bgs]: header + relative location + cgi + aliasmatch fails

ID: 19265 User updated by: steve@bluearena.com Reported By: steve@bluearena.com Status: Bogus Bug Type: Output Control Operating System: Linux PHP Version: 4CVS-2002-09-06 New Comment: I am trying to demonstrate that the same PHP code which works on the Apache module, fails with the CGI module. Both with Internet Explorer as the client.

For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. If people use incorrect (relative pathes) in the Location: header they cannot expect consistent behaviour. It may work in some browser and it may not work in others. ------------------------------------------------------------------------ [2002-09-07 06:28:24] steve@bluearena.com A relative location works most of the time. It always works with the Apache module, and the CGI version only fails when the aliasmatch directive is set. Anyway, I worked around this by using mod_rewrite instead of AliasMatch, so I'm not particularly bothered - but I'm quite sure that a lot of people use relative URIs with the Location header so it might be worth looking into. I realise the official standard says the URIs should be absolute, but IE, Netscape, and Lynx, maybe others, support relative.

You must use absolute URI for Location header. Try absolute URI, if it fixes. ------------------------------------------------------------------------ [2002-09-06 09:36:01] steve@bluearena.com I have run into a problem with the above setup on both the latest snapshot and also 4.2.2 - sorry if it's not a bug. <? if(!$test) die(header("Location: /?test=true")); else die("redirected ok: $REQUEST_URI"); ?> This works fine, and as expected, the output is: redirected ok: /?test=true However if I have the following lines in my httpd.conf: DocumentRoot /home/bla/html AliasMatch ^/sess/(.{4})/(.*) /home/bla/html/$2 And change the script to: <? if(!$test) die(header("Location: /sess/1234/?test=true")); else die("redirected ok: $REQUEST_URI"); ?> The output is: redirected ok: / I'm not quite sure what is going on here. I have just switched from an Apache module to CGI version for security reasons and wasn't quite expecting this problem so came into an interesting problem, a loop in my program, and crashes out with an error 500: GET / HTTP/1.0 host: www.mydomain.com HTTP/1.1 500 Internal Server Error Date: Fri, 06 Sep 2002 14:30:35 GMT Server: Apache/1.3.26 (Unix) PHP/4.2.2 mod_ssl/2.8.10 OpenSSL/0.9.6g X-Powered-By: PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3, PHP/4.2.3 Connection: close Content-Type: text/html; charset=iso-8859-1 Changing it to a absolute URL in the header("Location fixes the problem but it would be a pain to change this in all my scripts.
