Apache+Rails: malformed REQUEST_URI

[anonymous-matomo-user]

hello, i am experiencing some errors with the "Form security key" stuff when i want to login to piwik on my machine. I tracked down the error to the function "static public function getCurrentScriptName()" in Url.php

The $_SERVER['REQUEST_URI'] on my machine is not set correctly. instead of just /path/to/piwik/index.php it is set to http://www.some_host_i_am_using.com.local/path/to/piwik/index.php

i am not sure why this is the way it is so i just give you some hints:
i am on ubuntu lucid, with apache and php installed from repository.
piwik version is 0.6.3 but i also experienced this with earlier versions.
my virtual hosts file is not really interesting:

<VirtualHost *:80>
  ServerName www.some_host_i_am_using.com.local
  DocumentRoot /path/to/some/app/public
  RailsEnv development
</VirtualHost>

as you can see i am running a ruby on rails project. piwik is located in the public directory.

what is strange here: if i create a phpinfo file and call it via http://localhost/piwik/info.php the REQUEST_URI is set to "/piwik/info.php", when i call it via http://www.some_host_i_am_using.com.local/piwik/info.php i get REQUEST_URI set to "http://www.some_host_i_am_using.com.local/piwik/info.php"

i know this is not really a piwik related bug, but you could work around it :) my quickfix is to comment out the else if in Url.php where you try to check the REQUEST_URI (line 94). SCRIPT_NAME is set correct here and i am using this now.

I'll look into this, since I run Lucid on my dev box and haven't encountered this problem.

This appears to be a web server misconfiguration. Check your RewriteRules -- for example, make sure you don't have something like:

RewriteRule (.*) http://www.some_host_i_am_using.com.local/%{REQUEST_URI}
