Hi, I’ve recently compiled nginx 1.0.5 on localhost (debian), and have  
set up a test site so that i may access it [http://testsite](http://testsite) in the  
browser (set “testsite” to 127.0.0.1 in /etc/hosts and an nginx server  
config with root /var/www/testsite;)

i’ve been having some problems with some rewrites, and started pushing  
some of nginx vars out to php as fastcgi\_param’s to troubleshoot. i’ve  
noticed that $request\_filename is incorrect. it’s showing as  
“/var/www/testsiteindex.php” when accessing [http://testsite/foo/bar/](http://testsite/foo/bar/)  
(which is being redirected to index.php?q=foo/bar/).

i’m not sure if it’s my set up as I’m fairly new at this!

Thanks

$request\_filename will change when you rewrite the request, even if you  
just do an internal rewrite.  
$request\_filename is defined as root or alias directive + current URI.

So if you have a root defined as /var/www/testsite and you redirect to  
index.php then you’ll get /var/www/testsiteindex.php

URIs in Nginx always start with a / so it’s generally a good idea to  
rewrite to /index.php instead of index.php

Hi, thanks for the reply. Ok, so I’ve changed to /index.php, but  
$\_SERVER[‘SCRIPT\_FILENAME’] is now /var/www/testsite//index.php (double  
slash before index.php)

while the nginx $request\_filename is correct. Surely that isn’t right?

You probably have the directive

```
fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;

```

It should be changed to

```
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

```
